Description

Technical Field

[0001] This application relates to the field of laser equipment technology, and more specifically, to an optical structure adjustment device and a laser. Background Technology

[0002] In lasers and other optical devices, the combination structure of prisms and mirrors, as a key component of the resonant cavity, provides necessary optical feedback to the system, enabling stimulated emission photons to travel back and forth multiple times within the cavity and form stable laser oscillations, thereby effectively improving laser output power. In existing technologies, prisms and mirrors are typically rigidly connected at a fixed angle, with their structural parameters pre-designed and fabricated according to the target laser wavelength, making them suitable only for laser output at specific wavelengths. However, this fixed structure has significant limitations: when the laser output wavelength needs to be adjusted or applied to different types of lasers, a new optical combination structure must be redesigned and manufactured, leading to extended development cycles, significantly increased production costs, and poor versatility and flexibility. Therefore, a structurally sound, angle-adjustable, and highly precise optical component combination structure suitable for multiple wavelengths and types of lasers is needed to improve the adaptability, production efficiency, and mass production economics of lasers.

[0027] In lasers and other optical devices, the combination structure of prisms and mirrors, as a key component of the resonant cavity, provides necessary optical feedback to the system, enabling stimulated emission photons to travel back and forth multiple times within the cavity and form stable laser oscillations, thereby effectively improving laser output power. In existing technologies, prisms and mirrors are typically rigidly connected at a fixed angle, with their structural parameters pre-designed and fabricated according to the target laser wavelength, making them suitable only for laser output at specific wavelengths. However, this fixed structure has significant limitations: when the laser output wavelength needs to be adjusted or applied to different types of lasers, a new optical combination structure must be redesigned and manufactured, leading to extended development cycles, significantly increased production costs, and poor versatility and flexibility. Therefore, a structurally sound, angle-adjustable, and highly precise optical component combination structure suitable for multiple wavelengths and types of lasers is needed to improve the adaptability, production efficiency, and mass production economics of lasers.

[0028] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, to solve the above-mentioned technical problems, this application provides an optical structure adjustment device, which is disposed in the resonant cavity of a laser. The optical structure adjustment device includes a support assembly 100 and a first optical structure 101 and a second optical structure 102 arranged sequentially along the laser optical path. The support assembly 100 is provided with a first adjustment component 103 connected to the first optical structure 101, and the support assembly 100 is provided with a second adjustment component 104 connected to the second optical structure 102. The first adjustment component 103 and the second adjustment component 104 respectively drive the first optical structure 101 and the second optical structure 102 to rotate around a first direction, which is perpendicular to the laser optical path.

[0029] It should be noted that the optical structure adjustment device provided in this application embodiment is based on the design principle of tunable resonant cavity. By setting a first optical structure 101 and a second optical structure 102 with independently adjustable angles in the laser optical path and installing them on the bracket assembly 100 with a precision adjustment mechanism, dynamic control of the spatial orientation of optical elements is achieved.

[0030] It should be noted that, in operation, the first adjustment component 103 and the second adjustment component 104 drive the first optical structure 101 and the second optical structure 102 to rotate around an axis perpendicular to the laser light path, thereby precisely adjusting the refraction path of the light in the prism and the reflection angle of the mirror, and changing the propagation characteristics and feedback conditions of the beam in the resonant cavity. By coordinating the adjustment of the rotation angles of the two optical structures, the intracavity optical path matching can be optimized to meet the resonance conditions under different laser wavelengths, achieving multi-wavelength, highly stable laser oscillation output. This structure breaks through the limitations of traditional fixed optical components, significantly improving the wavelength adaptability, adjustment accuracy, and system flexibility of the laser.

[0031] The optical structure adjustment device provided in this application embodiment achieves precise and flexible control of the optical path angle within the resonant cavity by setting up an independently adjustable first optical structure 101 and a second optical structure 102, and equipping it with a high-precision rotation adjustment component. This device can dynamically optimize the spatial orientation of the prism and mirror in real time, ensuring efficient feedback and mode matching of lasers of different wavelengths within the cavity, significantly improving the wavelength adaptability and output stability of the laser. Compared to traditional fixed structures, this solution can adapt to various laser operating conditions without replacing optical components, effectively shortening the R&D cycle and reducing production costs. It also possesses advantages such as good repeatability and compact structure, significantly enhancing the versatility and adjustability of the laser system.

[0032] Reference Figure 1 , Figure 2As shown, in one optional embodiment, the bracket assembly 100 includes a first bracket 105, a second bracket 106, and a bracket adjustment structure; the bracket adjustment structure includes a bracket shaft 107 extending along a first direction and connecting the first bracket 105 and the second bracket 106, the bracket shaft 107 being used to drive the second bracket 106 to move around the first bracket 105; a first adjustment component 103 and a first optical structure 101 are mounted on the first bracket 105; a second adjustment component 104 and a second optical structure 102 are mounted on the second bracket 106.

[0033] It should be noted that, in this embodiment, the support assembly 100 is designed to include a first support 105, a second support 106, and a support adjustment structure connecting the two. The support shaft 107 extends along a first direction and drives the second support 106 to rotate relative to the first support 105, thereby achieving coordinated and independent adjustment of the two optical structures in spatial orientation. The first optical structure 101 and its first adjustment component 103 are mounted on the first support 105, and the second optical structure 102 and its second adjustment component 104 are mounted on the second support 106, allowing both to independently perform precise angular adjustments around the first direction under the support of their respective supports. Simultaneously, the introduction of the support shaft 107 allows the second support 106 to rotate relative to the first support 105 as a whole, thereby expanding the spatial adjustment range of the second optical structure 102 and enhancing the flexibility of the optical path configuration.

[0034] It should be noted that, in the operation of this embodiment, the angles of the respective optical elements are adjusted by controlling the first adjustment component 103 and the second adjustment component 104 respectively, and the orientation of the second support 106 can be adjusted as a whole by the support shaft 107, so as to achieve multi-dimensional precise control of the beam propagation path, reflection and refraction angles in the resonant cavity, optimize the intracavity mode matching and feedback efficiency, and meet the dynamic tuning requirements of multi-wavelength laser oscillation.

[0035] Reference Figure 2 , Figure 3 As shown, in one optional embodiment, the second support 106 includes a lower support 108 connected to the support shaft 107 and an upper support 109 mounted on the lower support 108; the lower support 108 and the upper support 109 are connected by a sliding assembly, and the upper support 109 is driven to move the second optical structure 102 and the second adjustment assembly 104 along a second direction; wherein, the second direction is perpendicular to the first direction.

[0036] It should be noted that, in this embodiment, a split structure consisting of a lower support 108 and an upper support 109 is provided in the second bracket 106, and a sliding assembly is used to realize the translational movement of the upper support 109 relative to the lower support 108 along the second direction, thereby providing additional linear adjustment freedom for the second optical structure 102 and its adjustment assembly. The lower support 108 is connected to the bracket pivot 107, allowing the entire second bracket 106 to rotate around the first direction; the upper support 109 is precisely moved along the sliding assembly in the second direction (perpendicular to the first direction) by an external drive (such as a fine-tuning screw or a piezoelectric actuator), driving the second adjustment assembly 104 and the second optical structure 102 to move synchronously. This embodiment not only retains the angle adjustment function of the second optical element but also introduces the ability to translate the spatial position, which can finely correct the alignment position and incident point of the beam in the resonant cavity, compensate for assembly errors or optical path offsets, and improve the optical path matching accuracy.

[0037] During operation, by coordinating the rotation of the support shaft 107, the angle adjustment of the second adjustment component 104, and the linear movement of the upper support 109, high-precision spatial positioning of the second optical structure 102 in multiple dimensions of angular and linear directions is achieved, significantly enhancing the adjustment flexibility and stability of the resonant cavity, and making it suitable for complex and ever-changing laser wavelength and mode requirements.

[0038] Reference Figure 2 , Figure 3 As shown, in one optional implementation, the sliding assembly includes a linear guide rail 110 and a linear drive module 111; the linear guide rail 110 is mounted on the lower support seat 108, and the upper support seat 109 is movably connected to the linear guide rail 110; the linear drive module 111 is mounted on the lower support seat 108 and is used to drive the upper support seat 109 to move on the linear guide rail 110.

[0039] It should be noted that, in this embodiment of the application, a sliding assembly is formed by setting a linear guide rail 110 and a linear drive module 111 on the lower support seat 108 of the second bracket 106, thereby achieving high-precision linear movement of the upper support seat 109 and the second optical structure 102 and the second adjustment assembly 104 along the second direction. The linear guide rail 110 provides a stable, low-friction guiding motion path for the upper support seat 109, ensuring straightness and repeatability during translation; the linear drive module 111 (such as a lead screw driven by a precision motor, a piezoelectric actuator, or a voice coil motor) provides a controllable driving force to push the upper support seat 109 to slide smoothly on the guide rail.

[0040] The structure in this embodiment, while maintaining the overall rotatability of the second support 106 around the first direction, further introduces a translational degree of freedom in the vertical direction. This allows for precise micrometer-level adjustment of the spatial position of the second optical structure 102, effectively correcting optical path offset, optimizing the beam incident point position, and improving the alignment accuracy and stability of the optical path within the resonant cavity. Through coordinated control with the angle adjustment component, precise linkage adjustment of optical elements under multiple degrees of freedom is achieved, significantly enhancing the laser's adaptability to different operating wavelengths and cavity structures.

[0041] Reference Figure 1 , Figure 2 As shown, in one optional implementation, the first adjustment assembly 103 includes a first rotating frame 112, a first rotating motor 113, and a first rotating shaft 114; the output end of the first rotating motor 113 is connected to the first rotating frame 112 through the first rotating shaft 114; the first optical structure 101 is mounted on the first rotating frame 112; the second adjustment assembly 104 includes a second rotating frame 115, a second rotating motor 116, and a second rotating shaft 117; the output end of the second rotating motor 116 is connected to the second rotating frame 115 through the second rotating shaft 117; the second optical structure 102 is mounted on the second rotating frame 115.

[0042] It should be noted that, in this embodiment, by setting independent drive structures consisting of a rotating motor, a rotating shaft, and a rotating frame on the first support 105 and the second support 106 respectively, high-precision and automated angle adjustment of the first optical structure 101 and the second optical structure 102 is achieved. Specifically, the first rotating motor 113 drives the first rotating frame 112 to rotate around a first direction via the first rotating shaft 114, causing the first optical structure 101 (e.g., a prism) mounted thereon to rotate synchronously; the second rotating motor 116 drives the second rotating frame 115 to rotate via the second rotating shaft 117, thereby adjusting the spatial angle of the second optical structure 102 (e.g., a reflector), and the second optical structure 102 is mounted on the second rotating frame 115 to ensure accurate transmission of the adjustment action. Each rotating motor can be a stepper motor or a servo motor in conjunction with a high-precision encoder to achieve precise control of minute angles. By controlling the rotation angles of the two motors separately, the incident / refractive angle of the prism and the reflection direction of the reflector in the optical path can be adjusted independently and precisely, optimizing the beam propagation path and feedback conditions within the resonant cavity. This structure combines direct motor drive with mechanical rotation mechanism, featuring fast response, good repeatability, and high adjustment accuracy. It facilitates laser wavelength tuning and automatic cavity alignment, significantly improving the intelligence and engineering practicality of optical adjustment.

[0043] For example, the first rotary motor 113 and the second rotary motor 116 can be high-resolution closed-loop stepper motors or torque servo motors, coupled with precision encoders, such as optical encoders or magnetic encoders, to achieve a resolution of 0.01° or higher, enabling precise position feedback. The first rotating shaft 114 and the second rotating shaft 117 adopt a highly concentric miniature precision bearing system, with surfaces ground to reduce radial runout (controlled within micrometers), and connected to the motor output end via a flexible coupling to compensate for assembly eccentricity and reduce transmission errors. Specifically, a closed-loop stepper motor with a resolution of 50,000 steps per revolution is used for drive, combined with a planetary reducer with a reduction ratio of 10:1, to achieve an equivalent angular resolution better than 0.0026°. Then, through micro-step subdivision and closed-loop correction by the control system, high-precision adjustment of the first and second optical structures 102 can be achieved within a range of ±180° with positioning accuracy at the arcsecond level, meeting the stringent requirements of the laser resonant cavity for fine optical path alignment and wavelength tuning.

[0044] Reference Figure 1 , Figure 2 As shown, as an optional implementation, the first adjustment component 103 is provided with a threaded hole extending in a first direction, and a threaded adjustment member 118 is provided in the threaded hole. One side of the first optical structure 101 abuts against the bearing surface provided on the first rotating frame 112, and the opposite side abuts against the threaded adjustment member 118.

[0045] It should be noted that, in this embodiment, a threaded hole extending in the first direction and a threaded adjusting member 118 are provided on the first adjusting component 103, forming an adjustable installation structure that combines clamping and fixing with size adaptation. One side of the first optical structure 101 is supported by the bearing surface of the first rotating frame 112, and the other side abuts against the end of the threaded adjusting member 118. Rotating the threaded adjusting member 118 achieves its axial lifting and lowering movement, thereby changing the clamping force on the optical element and achieving reliable clamping. Simultaneously, the stroke of the threaded adjusting member 118 is adjustable, accommodating optical elements of different thicknesses or heights. It flexibly adapts to various sizes of prisms and mirrors without changing the main structure, improving the versatility and replacement efficiency of the device. This structure, combined with the self-locking and fine-tuning characteristics of the precision threaded pair, not only ensures stable positioning of the optical element during adjustment, preventing loosening or displacement, but also, with pre-tightening force control, avoids overpressure damage to the optical surface, achieving safe, reliable, and high-precision clamping and installation, significantly enhancing the compatibility and practical flexibility of the optical adjustment device for diverse optical elements.

[0046] Similarly, the second adjustment component 104 is provided with a threaded hole extending in the first direction, and a threaded adjustment component 118 is provided in the threaded hole. One side of the second optical structure 102 abuts against the bearing surface provided on the second rotating frame 115, and the other side abuts against the threaded adjustment component 118.

[0047] As an optional implementation, the first optical structure 101 and the second optical structure 102 are provided with elastic structural members on the side near the threaded adjustment member 118; the threaded adjustment member 118 is in contact with the elastic structural member.

[0048] It should be noted that in this embodiment, elastic structural components (such as spring washers, wave washers, or miniature rubber pads) are provided on the side of the first optical structure 101 and the second optical structure 102 near the threaded adjustment component 118, and these components contact the threaded adjustment component 118 to form a flexible clamping and stress buffering structure. When the rotating threaded adjustment component 118 applies clamping force to the optical element, the elastic structural component undergoes elastic deformation under pressure, providing a controllable preload in the axial direction. This effectively eliminates the assembly gap between the optical element and the bearing surface, prevents loosening due to vibration or temperature changes, and improves installation stability and repeatability. Simultaneously, the elastic structural component can buffer the local pressure applied by the threaded adjustment component 118, avoiding stress concentration caused by rigid contact and protecting the surface of the optical element from damage. This is particularly suitable for fragile crystal prisms or high-precision mirrors. Furthermore, this structure, through its elastic compensation mechanism, can adapt to minute dimensional tolerances and deformations, further improving the compatibility and clamping reliability of the device for optical elements of different specifications, achieving safe, stable, and high-precision fixation and adjustment of optical elements.

[0049] The first optical structure 101 includes a prism; the second optical structure 102 includes a reflector.

[0050] This application provides a laser, including a resonant cavity, a discharge tube disposed in the resonant cavity, and the aforementioned optical structure adjustment device; the discharge tube, the first optical structure 101, and the second optical structure 102 are arranged along the optical path.

[0051] It should be noted that the laser provided in this application embodiment achieves high-precision and dynamic control of the laser resonant cavity optical path by sequentially arranging a discharge tube, a first optical structure 101, and a second optical structure 102 along the optical path within the resonant cavity, and integrating the aforementioned optical structure adjustment device. The discharge tube, acting as a gain medium, generates stimulated emission light. The light sequentially passes through the adjustable first optical structure 101 (such as a prism) and the second optical structure 102 (such as a mirror), and its propagation path and feedback characteristics are precisely controlled by their respective adjustment components. By driving the first and second rotating motors 116 and the auxiliary adjustment mechanism, the angle and position of the optical elements can be adjusted in real time, optimizing the refraction, reflection, and mode matching of the beam within the cavity, ensuring stable oscillation at different wavelengths. The structure of this application embodiment significantly improves the laser's wavelength tuning capability, optical path alignment accuracy, and operational stability. Simultaneously, the cooperation between the threaded adjustment component 118 and the elastic structure enhances the adaptability and clamping reliability of optical elements of different specifications. The overall solution achieves wide wavelength adaptation, rapid debugging, and high-stability output of the laser, effectively reducing the research and development and production costs of multiple laser models, and has good versatility, scalability, and engineering application value.
