Description

Technical Field

[0001] This application relates to the technical field of laser devices, and more particularly to a laser device. Background Technology

[0002] High-power semiconductor lasers, as the core pump source for fiber lasers and solid-state lasers, directly determine the output power, stability, and application scenarios of downstream lasers, making them a key core component in the field of laser technology.

[0003] Currently, the mainstream solution for high-power semiconductor lasers in the industry involves integrating multiple semiconductor laser units (COS) within a heat sink structure. High-power laser output is achieved by spatially arranging and shaping the beams output from each semiconductor laser unit. In practical applications, there are two main technical approaches to improving the output power of semiconductor lasers: first, by optimizing the chip structure and packaging process of the semiconductor laser unit to increase the power density of a single unit; second, by increasing the number of semiconductor laser units within the integration space allowed by the heat sink, and then achieving a total power increase through multi-unit beam combining.

[0004] However, as the output power of semiconductor laser modules continues to increase, the problem of stray light within them has become increasingly prominent and difficult to solve. Specifically, stray light mainly originates from two sources: first, unavoidable non-main beams that escape during the operation of the semiconductor laser unit itself; and second, ineffective beams generated by reflection, scattering, and transmission losses at the surfaces of various optical shaping devices in the optical path. Because the heat sink of a semiconductor laser requires sealing to ensure the cleanliness and stability of the internal components, the aforementioned stray light cannot escape to the outside and can only form cyclic reflections within the sealed heat sink. During cyclic reflection, the light energy of the stray light is continuously converted into heat energy, causing the internal temperature of the laser to rise continuously. This leads to a drift in the operating threshold of the semiconductor laser unit, a decrease in luminous efficiency, severely shortening the effective lifespan of high-power semiconductor lasers, and reducing their long-term operational reliability. This has become a key technical bottleneck restricting the development of high-power semiconductor lasers to higher power levels. Utility Model Content

[0005] The purpose of this application is to provide a laser device to solve the technical problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: On one hand, a laser device is provided, comprising: a base plate, a plurality of laser units, a light-transmitting cover, a photovoltaic power generation component, and a power supply component; the plurality of laser units are mounted on the base plate; the light-transmitting cover is mounted on the base plate and forms a sealed space between the cover and the base plate to accommodate the laser units; the photovoltaic power generation component is mounted on the light-transmitting cover and is capable of collecting stray light emitted through the light-transmitting cover and generating electrical energy; the power supply component is connected to the photovoltaic power generation component via a wire to transmit electrical energy.

[0007] Furthermore, the power supply component includes an energy storage unit and a management unit. The energy storage unit is connected to the solar power generation component through the management unit, and the management unit is also connected to the power supply equipment.

[0008] Furthermore, one end of the base plate is provided with an optical fiber fixing base, and the light-transmitting cover is provided with a first clearance groove to avoid the optical fiber fixing base.

[0009] Furthermore, two electrode fixing bases are provided at the other end of the base plate, and a second clearance groove is provided on the light-transmitting cover to avoid the electrode fixing bases.

[0010] Furthermore, the optical fiber fixing base and the electrode fixing base are integrally formed on the base plate.

[0011] Furthermore, the connection between the base plate and the light-transmitting cover is coated with sealant or equipped with a sealing ring.

[0012] Furthermore, the material of the light-transmitting cover is quartz glass.

[0013] Furthermore, the light-transmitting cover includes four circumferentially arranged side plates and a top plate connected to the upper end of the four side plates, and the solar power generation components are respectively disposed on the side plates and the top plate.

[0014] Furthermore, the photovoltaic power generation component includes multiple photovoltaic elements arranged in an array.

[0015] Furthermore, the base plate is made of copper.

[0016] The beneficial effects of this application are as follows: by using a photovoltaic power generation component to directionally capture and convert stray light in a sealed space into resources, the drawback of the traditional sealed structure where stray light is cyclically reflected and converted into heat energy is completely changed. This effectively blocks the path of continuous temperature rise inside the laser, avoids problems such as working threshold drift and luminous efficiency reduction caused by high temperature in the laser unit, significantly improves the long-term working stability of the high-power laser device, and greatly extends the effective service life and reliability of the laser unit and the entire device.

[0020] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1-4 As shown, this embodiment provides a laser device, including: a base plate 1, multiple laser units 2, a light-transmitting cover 3, a photovoltaic power generation component 4, and a power supply component 5; the multiple laser units 2 are mounted on the base plate 1; the light-transmitting cover 3 is mounted on the base plate 1, and a sealed space is formed between the cover 3 and the base plate 1 to accommodate the laser units 2; the photovoltaic power generation component 4 is mounted on the light-transmitting cover 3, and the photovoltaic power generation component 4 can collect stray light emitted through the light-transmitting cover 3 and generate electrical energy; the power supply component 5 is connected to the photovoltaic power generation component 4 through wires to transmit electrical energy.

[0024] Based on the above scheme, multiple laser units 2 are fixed on the base plate 1, and the light-transmitting cover 3 and the base plate 1 are encapsulated to form a sealed space. This not only continues the existing technology's requirements for the cleanliness and operational stability of the laser unit 2, but also provides a channel for stray light to be discharged through the light-transmitting characteristics of the light-transmitting cover 3. When the laser unit 2 is working, in addition to the output target main beam, the stray light that is inevitably generated (including the non-main beam emitted by the laser unit 2 itself and the invalid beam lost during the optical shaping process) is confined within the sealed space and cannot be randomly emitted to the outside. The light-transmitting cover 3 allows stray light to penetrate and be projected onto the photovoltaic power generation component 4 installed on its outside. This component directly converts the captured stray light energy into electrical energy. The photovoltaic power generation component 4 is connected to the power supply component 5 through wires. The converted electrical energy is transmitted to the power supply component 5 for storage or secondary use, completing the closed loop of stray light conversion from invalid light energy to usable electrical energy.

[0025] This laser device uses a photoelectric power generation component 4 to directionally capture and convert stray light within a sealed space, completely overcoming the drawback of traditional sealed structures where stray light is cyclically reflected and converted into heat energy. This effectively blocks the path of continuous temperature increase inside the laser, avoiding problems such as operating threshold drift and decreased luminous efficiency caused by high temperatures in laser unit 2. It significantly improves the long-term operational stability of the high-power laser device, greatly extending the effective service life and reliability of laser unit 2 and the entire device, providing a core guarantee for the development of lasers to higher power levels. Furthermore, it converts stray light, which was originally wasted and had negative impacts, into usable electrical energy, improving… This improves the energy utilization rate of the entire laser system, reduces energy consumption, and conforms to the technological development trend of energy conservation and environmental protection. At the same time, the recovered electrical energy can be used to power the auxiliary functions of the device itself or stored for backup, further optimizing the energy configuration of the system. The sealed space formed by the light-transmitting cover 3 and the base plate 1 can still ensure the cleanliness of the laser unit 2 and the internal optical components, avoiding interference from the external environment. Meanwhile, the newly added photovoltaic power generation component 4 is integrated on the light-transmitting cover 3, with a compact structure that does not require a large amount of additional installation space and does not affect the overall layout of the laser device and the normal transmission of the main beam. It achieves functional upgrades while ensuring the original sealing advantages, and is highly practical.

[0026] Specifically, the power supply component 5 includes an energy storage unit and a management unit. The energy storage unit is connected to the photovoltaic power generation component 4 through the management unit, and the management unit is also connected to the power supply equipment 6. The electrical energy converted by the photovoltaic power generation component 4 is first transmitted to the management unit through a wire. The management unit performs preliminary voltage stabilization and rectification on the electrical energy, adjusting it to an electrical energy form (such as DC power) that meets the storage standards of the energy storage unit. Subsequently, the electrical energy is delivered to the energy storage unit (such as a lithium battery pack, supercapacitor, etc.) for storage, realizing a temporary buffer for the conversion of stray light into electrical energy and avoiding unstable power supply caused by fluctuations in stray light intensity. As a core control module, the management unit has functions such as power monitoring, charge and discharge control, and overload protection. On the one hand, it monitors the power status of the energy storage unit in real time (such as remaining power and charging progress). When the power of the energy storage unit reaches the preset upper limit, it controls the charging to stop to avoid damage from overcharging. When the power is lower than the preset threshold, it can coordinate with the power supply equipment 6 to supplement the power supply. On the other hand, based on the power demand of the laser device, the energy stored in the energy storage unit is intelligently allocated to prioritize the power needs of auxiliary circuits and other loads, achieving efficient energy dispatch. The management unit is connected to the external power supply device 6, forming a dual power supply mode. When the energy converted from stray light is sufficient, it can independently power the load or charge the energy storage unit. When the stray light intensity is insufficient and the converted energy cannot meet the demand, the external power supply device 6 replenishes the energy in a timely manner through the management unit, ensuring the stable operation of key components of the laser device and avoiding the impact of power outages on operation.

[0027] In some embodiments, an optical fiber fixing base 11 is provided at one end of the base plate 1, and a first clearance groove 34 is provided on the light-transmitting cover 3 to avoid the optical fiber fixing base 11. The optical fiber fixing base 11 is used to stably fix the optical fiber components matched with the laser unit 2, such as the output optical fiber and the coupling optical fiber, to ensure the optical path alignment accuracy between the optical fiber and the laser unit 2, and to ensure that the main beam can be efficiently coupled to the optical fiber and transmitted. It is a key structure for the laser device to achieve the target beam output. As a key component of the sealed space, the light-transmitting cover 3 needs to be tightly fitted with the base plate 1 to ensure the sealing effect. However, the presence of the optical fiber fixing base 11 will cause structural interference between the light-transmitting cover 3 and the base plate 1. To this end, a first clearance groove 34 is provided on the light-transmitting cover 3 at the position corresponding to the fiber optic fixing base 11. The shape and size of the groove match the outer contour of the fiber optic fixing base 11, so that the groove can accurately accommodate the fiber optic fixing base 11 when the light-transmitting cover 3 is installed, avoiding mechanical collision or squeezing between the two, while ensuring that the light-transmitting cover 3 fits tightly with other areas of the base plate 1. Through the clearance design of the first clearance groove 34, the light-transmitting cover 3 and the base plate 1 can still form a complete sealed space without affecting the normal installation and operation of the fiber optic fixing base 11. This not only ensures the clean working environment required by the laser unit 2, but also avoids the sealing failure problem caused by structural interference, and realizes the compatibility and synergy of fiber optic fixing function and sealing function.

[0028] Meanwhile, two electrode fixing bases 12 are provided at the other end of the base plate 1, and a second clearance groove 33 is provided on the light-transmitting cover 3 to avoid the electrode fixing bases 12. The second clearance groove 33 is precisely designed for the layout of the two electrode fixing bases 12, effectively avoiding mechanical interference between the light-transmitting cover 3 and the electrode fixing base 12. This ensures that the light-transmitting cover 3 can be installed smoothly and accurately, preventing scratches and squeezing damage to components during assembly. At the same time, it ensures the installation firmness of the electrode fixing base 12, providing structural support for the smooth assembly of the laser device. The stable fixing of the electrode fixing base 12 is the foundation for the laser unit 2 to obtain a continuous and stable power supply. The design of the second clearance groove 33 does not change the installation method and position of the electrode fixing base 12, ensuring the accuracy and stability of the electrical connection between the electrode and the laser unit 2, and avoiding the impact of power supply fluctuations on the laser output performance. At the same time, the matching design of the groove and the electrode fixing base 12 ensures that the light-transmitting cover 3 and the base plate 1 are tightly fitted, ensuring the integrity of the sealed space and effectively isolating external dust, moisture and other interference, providing a clean and stable working environment for the laser unit 2 and electrode components, and improving the electrical safety of the device. The fiber optic fixing base 11 and the electrode fixing base 12 are integrally formed on the base plate 1. This integral design completely eliminates the risks of loosening and displacement that might occur with separate assembly of the fiber optic fixing base 11, electrode fixing base 12, and base plate 1. The base and base plate 1 form a stable overall structure that can withstand external influences such as vibration and temperature changes during laser device operation, ensuring the accuracy of fiber fixing and the stability of electrode connection. This avoids problems such as optical path deviation and poor power supply contact caused by base loosening, significantly improving the structural reliability of the laser device. The integral molding process allows for higher dimensional tolerance control and positional accuracy control, precisely ensuring the relative spacing between the fiber optic fixing base 11 and electrode fixing base 12, as well as their positional compatibility with the laser unit 2 mounting position. This provides a reliable structural benchmark for the efficient coupling of the laser unit 2 and the fiber optic cable, and the precise electrical connection between the electrode and the laser unit 2, helping to improve the main beam output efficiency and power supply stability, and reducing performance loss due to assembly errors.

[0029] It is worth noting that the connection between the base plate 1 and the light-transmitting cover 3 is coated with sealant or equipped with a sealing ring. Although the connection surfaces of the base plate 1 and the light-transmitting cover 3 are precision-machined, microscopic gaps or uneven structural defects still exist. When sealant is used, its excellent fluidity and adhesion allow it to fully fill the microscopic gaps on the connection surfaces, forming a strong bond with the base plate 1 and the light-transmitting cover 3 after curing. When a sealing ring is used, its elastic deformation characteristics are utilized; under the assembly pressure of the light-transmitting cover 3 and the base plate 1, the sealing ring is compressed and tightly conforms to the contour of the connection surfaces, achieving physical sealing of the gaps. The sealant or sealing ring forms a continuous, gapless sealing barrier at the connection point, blocking the gas flow path between the sealed space and the external environment. On the one hand, it prevents dust, water vapor, particulate matter and other impurities in the outside air from entering the sealed space, and avoids them from adhering to the surface of the laser unit 2 and the photovoltaic power generation component 4, thus affecting the optical performance and power conversion efficiency; on the other hand, it prevents stray light in the sealed space from escaping outward through the connection gap, and ensures that stray light can be captured by the photovoltaic power generation component 4 to the maximum extent, thus ensuring energy recovery efficiency.

[0030] The application of sealant or sealing rings does not alter the main structure and assembly method of the base plate 1 and the light-transmitting cover 3, and can cooperate with the first and second clearance grooves 33 on the light-transmitting cover 3. While avoiding the optical fiber fixing base 11 and the electrode fixing base 12, the sealing medium provides auxiliary sealing to the contact area between the groove and the base, further improving the overall sealing effect.

[0031] Optionally, the transparent cover 3 is made of quartz glass. Quartz glass has the characteristics of high transmittance over a wide spectrum and low optical loss, allowing stray light generated during the operation of the laser device (covering common wavelengths of semiconductor lasers) to efficiently pass through the transparent cover 3 and be accurately projected onto the external photovoltaic component 4, providing the necessary optical path for the capture of stray light and the conversion of electrical energy. At the same time, its excellent light transmittance will not cause additional attenuation to the main beam output by the laser unit 2, ensuring the normal transmission and utilization of the main beam. In addition, quartz glass has good mechanical strength and resistance to high and low temperatures, and can adapt to temperature changes during the operation of high-power laser devices, such as heat conduction in the sealed space and fluctuations in the external ambient temperature, and is not easily deformed or cracked due to thermal expansion and contraction. Moreover, its strong chemical stability can resist the erosion of external dust, water vapor and corrosive gases, and together with sealant or sealing ring, it forms a reliable sealing barrier to ensure the cleanliness of the internal laser unit 2 and the optical path.

[0032] Generally, the light-transmitting cover 3 includes four circumferentially arranged side plates 31 and a top plate 32 connected to the upper ends of the four side plates 31. The photovoltaic power generation components 4 are respectively disposed on the side plates 31 and the top plate 32. The photovoltaic power generation components 4 are evenly distributed on the side plates 31 and the top plate 32 of the light-transmitting cover 3, realizing the all-dimensional capture of stray light in the sealed space. This completely solves the problem of stray light escaping due to differences in propagation direction under a single planar layout, significantly improving the stray light capture rate and total electrical energy conversion, further reducing the ineffective energy loss of the laser device, and optimizing the system's energy utilization rate. The light-transmitting cover 3 adopts an integrated structural design of the four side plates 31 and the top plate 32. The photovoltaic power generation components 4 are directly integrated on its surface, eliminating the need for additional independent stray light receiving brackets. This fully utilizes the protective space and surface area of ​​the light-transmitting cover 3, avoids occupying the external installation space of the laser device, realizes the space reuse of sealing protection and energy recovery functions, and improves the overall integration and compactness of the device. The solar power generation modules 4 are distributed on the side plate 31 and the top plate 32, which can avoid local overheating caused by concentrated reception of stray light in a single area. The heat is evenly dissipated through the surfaces of multiple modules, reducing the operating temperature of a single module and effectively alleviating the problem of conversion efficiency degradation caused by high temperature of the solar power generation modules 4, thus extending the service life of the modules.

[0033] The photovoltaic power generation component 4 includes multiple photovoltaic elements arranged in an array. These elements are distributed in a regular array (e.g., rectangular array, honeycomb array) on the side plates 31 and top plate 32 of the light-transmitting cover 3, fully filling the light-transmitting area of ​​the cover and eliminating blind spots in single or dispersed arrangements, forming a continuous and seamless light-capturing surface. Stray light within the sealed space is randomly scattered; stray light of different directions and intensities penetrates the cover 3 and is accurately received by the corresponding photovoltaic elements. Each photovoltaic element independently completes the light-to-electricity conversion, then collects the electrical energy through parallel or series connections and transmits it to the power supply component 5, achieving coordinated energy recovery from multiple sources and avoiding energy recovery failure due to partial obstruction or damage to a single large-sized photovoltaic component. The array arrangement allows for flexible adjustment of the number and spacing of photoelectric components according to the size and shape of the side plate 31 and top plate 32 of the light-transmitting cover 3, adapting to the structural boundary of the clearance groove without affecting the clearance fit between the light-transmitting cover 3 and the base; at the same time, the heat dissipation path of the small-sized photoelectric components is shorter, which can quickly dissipate the heat generated during the light energy conversion process and reduce the conversion efficiency loss caused by local overheating.

[0034] Preferably, the base plate 1 is made of copper. The high thermal conductivity of the copper base plate 1 significantly improves the heat dissipation efficiency of the laser device, which can quickly dissipate the working heat and residual stray light heat of the laser unit 2, effectively suppress the temperature rise in the sealed space, and avoid problems such as threshold drift and luminous efficiency decay of the laser unit 2 due to high temperature. This significantly improves the output power stability and long-term operational reliability of the laser device, and provides thermal management protection for the development of lasers to higher power levels.

[0035] In some embodiments, multiple vertically parallel steps are machined on both sides of the base plate 1. The surface of each step serves as the mounting reference surface for the laser unit 2. The laser units 2 on both sides are symmetrically arranged and their light-emitting directions are opposite. This stepped structure can achieve multi-level dense arrangement of laser units 2 within the limited space of the base plate 1, significantly increasing the number of laser units 2 integrated per unit volume. At the same time, the opposite light-emitting directions provide the basic optical path conditions for the subsequent beam combining of the two sides, avoiding the optical path extension and energy loss caused by the single-sided layout. Each laser unit 2 is equipped with a fast-axis collimating lens and a slow-axis collimating lens in its light-emitting direction. The two sets of lenses compress and correct the divergence angles of the output beam of the laser unit 2 in the fast-axis and slow-axis directions, respectively. The original output beam of the laser unit 2 is an asymmetric divergent beam with a large divergence angle in the fast-axis direction and a small divergence angle in the slow-axis direction. After the synergistic effect of the fast-axis collimating lens and the slow-axis collimating lens, the divergent beam is shaped into a highly parallel collimated beam, providing a highly consistent beam source for subsequent reflection and beam combining.

[0036] Furthermore, the array of reflecting mirrors behind the slow-axis collimating lens corresponds one-to-one with the laser units 2 on each step. This allows the collimated single-sided beams to be reflected at a uniform angle, forming a parallel light array with consistent direction and uniform spacing from the dispersed single collimated beams. The parallel light arrays on both sides are then guided a second time by a large reflecting mirror, achieving spatial convergence of the two beams and creating coaxial or near-coaxial incident conditions for polarization beam combining. The converged two beams are then combined by a polarization mirror, using the principle of polarization beam splitting to superimpose beams of different polarization states, effectively increasing laser power. The combined parallel beam has two flexible output modes: first, it can be output directly as parallel light without a focusing lens and fiber, suitable for long-distance irradiation, surface treatment, and other scenarios where fiber transmission is not required; second, the combined parallel light can be focused by a focusing lens group and coupled into an optical fiber, achieving flexible transmission of laser energy, suitable for applications requiring fiber transmission such as precision machining and laser medicine.
