Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser equipment technology, and in particular to an all-in-one laser device. Background Technology
[0002] Existing multi-wavelength beam combining semiconductor lasers typically employ at least one dichroic mirror for each laser to reflect the current laser beam and transmit the beam emitted by the previous laser, thus achieving laser beam combining. However, due to the high optical loss of dichroic mirrors, the laser beam's light utilization is significantly reduced after transmission through them. This is especially true for lasers located far from the output port, where the laser beam must pass through multiple or even all of the dichroic mirrors, resulting in a more significant impact on the intensity of the emitted beam. Furthermore, the aforementioned dichroic mirror beam combining scheme severely affects the beam combining of low-power, long-wavelength lasers. In addition, dichroic mirrors have certain wavelength selectivity requirements, limiting the selection of the laser beam combining wavelength. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0050] The following description, in conjunction with the accompanying drawings, introduces an embodiment of the present invention providing an all-in-one laser device. Please refer to the accompanying drawings. Figure 1-7 The all-in-one laser device includes a laser emitting component, an optical path mechanism, an optical path switching mechanism, and an output port 11.
[0051] refer to Figure 1The laser emitting assembly includes at least two laser emitting sources 21 for emitting laser beams. The wavelengths of the laser beams emitted by each laser emitting source 212 can be the same or different. In some embodiments, the at least two laser emitting sources 21 are capable of emitting laser beams of at least two wavelengths. Preferably, the wavelengths of the laser beams emitted by each laser emitting source 21 are different from each other, and the selectable wavelengths are not limited.
[0052] The optical path mechanism includes at least two first optical path adjustment components 22, which are arranged one-to-one with the laser emission source 21 and are located in the output optical path of the laser emission source 21. They are used to adjust the incident laser beam so that the laser beam that can be projected onto the first reflector 23 is emitted, and finally the collinear output of all laser emission sources 21 is achieved.
[0053] The optical path switching mechanism includes a first reflector 23 and a moving mechanism 24 connected to the first reflector 23. The moving mechanism 24 can drive the first reflector 23 to move relative to each first optical path adjustment component 22, so as to switch the first reflector 23 to the output optical path of each first optical path adjustment component 22, thereby receiving the laser beam projected by the currently aligned first optical path adjustment component 22. In one embodiment, the first reflector 23 is a total reflection mirror.
[0054] The light outlet 11 is located in the projection optical path of the first reflector 23. The laser beam emitted from the laser source 21 can be projected to the first reflector 23 through the first optical path adjustment component 22, and then projected to the light outlet 11 after being reflected by the first reflector 23. The optical paths of the laser beams of each laser source 21 after being reflected by the first reflector 23 are collinear, that is, the laser beams projected by each first optical path adjustment component 22 can be output collinearly after being reflected by the first reflector 23.
[0055] In summary, the multi-functional laser device of this application includes a first reflector 23 and a moving mechanism 24 for optical path switching. The moving mechanism 24 drives the first reflector 23 to move relative to each first optical path adjustment component 22 to switch the output optical path of the first reflector 23 to each first optical path adjustment component 22, thereby projecting the laser beams of each laser emission source 21 to the output port 11. In this way, the laser beam switching of different laser emission sources 21 is realized through the optical path switching mechanism. Compared with the traditional method of output beams through multiple dichroic mirrors, it significantly reduces light intensity loss, improves light utilization, and avoids the limitation of wavelength selection of laser emission source 21, and can flexibly adapt to laser beams of various wavelengths.
[0056] In some embodiments, reference is made to Figure 1The moving mechanism 24 can drive the first reflector 23 to perform linear motion to switch the first reflector 23 to the output optical path of each first optical path adjustment component 22, thereby receiving and reflecting the laser beams of each laser emitting source 21 respectively. The linear motion of the first reflector 23 ensures the laser switching and collinear output of different laser emitting sources 21, while improving the movement control accuracy of the first reflector 23 and reducing the difficulty of adjusting the optical path of the laser beam output.
[0057] In some embodiments, at least two laser emitting sources 21 are arranged in parallel, that is, adjacent to each other in a row, with the emitting end 211 of each laser emitting source 21 facing the optical path mechanism. Preferably, at least two laser emitting sources 21 are arranged adjacent to each other in sequence to reduce the occupied size.
[0058] In other embodiments, reference is made to Figure 1 At least two laser emission sources 21 are arranged in an alternating manner, with the position of any one laser emission source 21 avoiding the emission optical path of the other laser emission sources 21. The alternating arrangement means that at least two laser emission sources 21 are arranged along at least two rows, preferably with partial stacking of laser emission sources 21 in adjacent rows, to reduce space occupation, significantly reduce the unidirectional size of the system, and not affect heat dissipation. Simultaneously, in rows near the optical path mechanism, adjacent laser emission sources 21 arranged in the same row are spaced apart to avoid blocking the emitting end 211 of the laser emission source 21 in the next row.
[0059] In some embodiments, reference is made to Figure 1 The output optical paths of each laser emitter 21 are arranged at intervals and parallel to each other. Each first optical path adjustment component 22 is located between each laser emitter 21 and the optical path switching mechanism. The laser beams emitted from each laser emitter 21 are projected onto their respective first optical path adjustment components 22 along parallel output optical paths, which is beneficial for the positional arrangement of each laser emitter 21 and simplifies the modulation of each laser beam. Preferably, the emitting end 211 of each laser emitter 21 is oriented towards the optical path mechanism.
[0060] In some embodiments, reference is made to Figure 1 and Figure 2 The outgoing optical paths of each first optical path adjustment component 22 are arranged at intervals and parallel to each other. That is, the laser beams of each laser emission source 21 form multiple parallel beams after passing through each first optical path adjustment component 22, which simplifies the switching path setting of the optical path switching mechanism, thereby improving the projection accuracy of the first reflector 23 for each laser beam and the linearity of the optical path. Preferably, the outgoing optical paths of each first optical path adjustment component 22 are parallel to each other and coplanarly arranged to further ensure the consistency of the position of each laser beam incident on the first reflector 23 and the projection accuracy. Preferably, the structures of each first optical path adjustment component 22 are consistent, and the optical path assembly is simplified through modular unified design.
[0061] Understandably, in existing dichroic mirror beam combining schemes, long-wavelength light sources such as infrared light need to be placed far away from the light output port 11, while short-wavelength laser sources need to be placed close to the light output port 11. However, in the scheme of this application, a reflection method is used for beam combining, which not only avoids energy loss during the laser beam emission process, but also allows for flexible adjustment and installation of laser emission sources 21 of various wavelengths, without being limited by the position of the light output port 11, thereby improving the flexibility of laser source integration.
[0062] In some embodiments, reference is made to Figure 1 The moving mechanism 24 includes a driving device (not shown), a sliding component 241 that is driven by the driving device, and a guide component that is slidably connected to the sliding component 241. The first reflector 23 is disposed on the sliding component 241. The driving device can drive the sliding component 241 to slide relative to the guide component, thereby moving the first reflector 23. The guide component limits the direction of movement of the first reflector 23. Thus, under the driving action of the driving device, the sliding component 241 and the first reflector 23 switch along the direction of movement limited by the guide component in the output optical path of each first optical path adjustment component 22, accurately controlling the movement path and position of the first reflector 23, and ensuring the switching and projection accuracy of different laser beams.
[0063] In one embodiment, the guide component 242 may include a slide rail, and the sliding component 241 may include a slider that matches the slide rail. The sliding of the moving component relative to the guide component is achieved through the cooperation of the slide rail and the slider. It is understood that the guide component 242 and the sliding component 241 in this application may also adopt other sliding connection methods, and are not limited to the above description.
[0064] Preferably, the direction of movement defined by the guide component 242 is a straight line, so that the driving device can drive the sliding component 241 to slide along a straight line relative to the guide component, thereby driving the first reflector 23 to move in a straight line, which is beneficial to the collinear output of each laser beam and the control accuracy.
[0065] In some embodiments, the first optical path adjustment component 22 forms a reflected optical path for the projected laser beam. Optionally, the first optical path adjustment component 22 forms a total internal reflection optical path for the projected laser beam, that is, a total internal reflection mirror is used as an adjustment element in the adjustment optical path, so that the entire optical path of the laser beam adopts total internal reflection transmission, which significantly reduces light energy loss and can be adapted to lasers of any wavelength.
[0066] In some embodiments, reference is made to Figure 2The first optical path adjustment assembly 22 includes a second reflector 222, a third reflector (not shown), and a first adjustment frame 221. The first adjustment frame 221 is connected to the second reflector 222 and the third reflector respectively, and can adjust the position and incident angle of the second reflector 222 and the third reflector, thereby precisely modulating the laser beam emitted from each of the first optical path adjustment assemblies 22, and achieving high-precision alignment with the first reflector 23. Specifically, refer to... Figure 2 At least two first adjustment brackets 221 can be set to correspond to the second reflector 222 and the third reflector respectively. The second reflector 222 and the third reflector can be adjusted by different first adjustment brackets 221, thereby decoupling the position and incident angle adjustment of different reflectors.
[0067] Based on some or all of the above embodiments, in some embodiments, reference is made to Figure 3-5 The all-in-one laser device also includes a cooling mechanism 3, which includes a heat-conducting component 31. The laser emitting components are mounted on the heat-conducting component 31, meaning that each laser emitting source 21 is integrated and installed on the heat-conducting component 31 to achieve overall heat dissipation of the laser emitting components. This eliminates the need for a separate heat dissipation module for each laser emitting source 21, increases the heat dissipation area, and is suitable for air-cooled structures, ensuring effective heat dissipation. Compared to water cooling, this air-cooling method reduces the space occupied by the cooling mechanism 3 and avoids the risk of water leakage.
[0068] In some embodiments, the cooling mechanism 3 further includes an air-cooled radiator, with the heat-conducting element 31 disposed in the effective cooling area of the air-cooled radiator to facilitate cooling of the laser emitting component. Specifically, the air-cooled radiator can be a silent cooling fan, etc.
[0069] Specifically, refer to Figure 3-5 The heat-conducting component 31 can be a heat dissipation fin with a plate-like shape on one side. The air-cooled heat sink is located on one or both sides of the heat dissipation fin to achieve air cooling. At least two laser emission sources 21 are staggered on the heat-conducting component 31, which is conducive to reducing the system size while ensuring heat dissipation.
[0070] Based on some or all of the above embodiments, in some embodiments, reference is made to Figure 1 The all-in-one laser device also includes a reference light source 25 for emitting a reference beam, which is used for adjusting and positioning the projection position of the laser beam.
[0071] Correspondingly, the optical path mechanism also includes a second optical path adjustment component 26 disposed on the outgoing optical path of the reference light source 25, for receiving the reference beam and projecting it onto the first reflector 23; the moving mechanism 24 can drive the first reflector 23 to move relative to the second optical path adjustment component 26 to switch the outgoing optical path of the first reflector 23 to the second optical path adjustment component 26, thereby achieving alignment of the projected optical path.
[0072] The reference beam emitted from the reference light source 25 can be projected onto the first reflector 23 via the second optical path adjustment component 26, and then reflected by the first reflector 23 before being projected onto the light outlet 11. The reference beam and the laser beam are collinear after being reflected by the first reflector 23. In this way, the collinear output of the reference beam and the laser beam is achieved by combining the second optical path adjustment component 26, the moving mechanism 24, and the first reflector 23, and the precise positioning of the laser beam in the projection area is realized. This facilitates the adjustment and operation of invisible light sources such as those in the near-infrared and mid-infrared bands, and improves the safety of equipment use.
[0073] In some embodiments, the reference light source 25 and each laser emission source 21 are arranged in an alternating manner, and the reference light source 25 and the laser emission source 21 avoid each other's outgoing light paths. In this way, the light source occupancy is further optimized, and the unidirectional size of the device is reduced.
[0074] In some embodiments, reference is made to Figure 4 The reference light source 25 and the laser emitting components are integrated on the heat-conducting component 31 to dissipate heat from the reference light source 25 and each laser emitting source 21 as a whole, thereby optimizing the structural design of the equipment and improving heat dissipation efficiency.
[0075] Understandably, with the combination of the moving mechanism and the first reflector 23, the location of the reference light source 25 is unrestricted, such as being located between the laser emitting sources 21 or on one side of the laser emitting assembly, thus improving assembly flexibility. Preferably, the reference light source 25 is located on the side of the laser emitting assembly closer to the light exit port 11, that is, the reference light source 25 is closer to the light exit port 11 than the laser emitting sources 21, to facilitate the assembly, beam modulation, and calibration of the laser emitting sources 21.
[0076] In some embodiments, reference is made to Figure 1 The reference light source 25 and each laser emission source 21 are arranged at intervals and parallel to each other. The second optical path adjustment component 26 is located between the reference light source 25 and the optical path switching mechanism. The reference beam emitted by the reference light source 25 and the laser beam emitted by each laser emission source 21 are projected onto the second optical path adjustment component 26 and each first optical path adjustment component 22 respectively along the parallel emission optical paths. This is beneficial to the position arrangement of the reference light source 25 and each laser emission source 21 and simplifies the movement control of the optical path switching mechanism.
[0077] In some embodiments, reference is made to Figure 2The outgoing optical paths of the first optical path adjustment components 22 and the second optical path adjustment components 26 are arranged at intervals and parallel to each other. That is, after the reference beam passes through the second optical path adjustment component 26, the laser beams of each laser emission source 21 pass through the first optical path adjustment components 22 to form parallel beams. This simplifies the switching path setting of the optical path switching mechanism, thereby improving the projection accuracy and optical path linearity of the first reflector 23 for the reference beam and each laser beam. Preferably, the outgoing optical paths of the second optical path adjustment components 26 and the first optical path adjustment components 22 are parallel to each other and coplanar, to further ensure the consistency of the position and projection accuracy of the reference beam and laser beam incident on the first reflector 23. Preferably, the second optical path adjustment components 26 and the first optical path adjustment components 22 have the same structure, simplifying optical path assembly through a modular and unified design.
[0078] In some embodiments, the second optical path adjustment component 26 forms a reflected optical path for projecting the reference beam. Optionally, the second optical path adjustment component 26 forms a total internal reflection optical path for projecting the reference beam, that is, a total internal reflection mirror is used as an adjustment element in the adjustment optical path, so that the entire optical path of the reference beam adopts total internal reflection transmission, which significantly reduces light energy loss and can be adapted to light sources of any wavelength, while ensuring the transmission consistency between the reference beam and the laser beam, which is beneficial to simplifying optical path assembly and reducing calibration difficulty.
[0079] In some embodiments, the second optical path adjustment assembly 26 includes a fourth reflector 262, a fifth reflector (not shown), and a second adjustment frame 261. The second adjustment frame 261 is connected to the fourth reflector 262 and the fifth reflector, respectively, and can adjust the position and incident angle of the fourth reflector 262 and the fifth reflector, thereby precisely modulating the reference beam emitted by the second optical path adjustment assembly 26 and achieving optical path alignment with the first reflector 23. Specifically, at least two second adjustment frames 261 can be provided, corresponding to the fourth reflector 262 and the fifth reflector respectively. By adjusting the fourth reflector 262 and the fifth reflector separately using different second adjustment frames, the position and incident angle adjustment of different reflectors can be decoupled.
[0080] Based on some or all of the above embodiments, in some embodiments, reference is made to Figure 7 The all-in-one laser device also includes a control board and a touch screen. The touch screen, laser emitting component, optical path switching mechanism and touch screen are electrically connected to the control board to realize integrated control of the all-in-one device. The touch screen can also be used for offline operation of the laser device, realizing plug and play.
[0081] In some embodiments, reference is made to Figure 6 and Figure 7 The control board is also connected to control interface 41 for connecting external control devices, etc.
[0082] Specifically, refer to Figure 7 The dashed arrows in the diagram represent optical paths. The control board receives control signals to control the opening and closing of each laser emitter 21 and reference light source 25, and to control the position switching mechanism between the output optical paths of each optical path adjustment component. Before emitting the laser beam, the reference light source 25 can be turned on and emit a reference beam. At the same time, the moving mechanism 24 is controlled to move the first reflector 23 linearly to the output optical path of the second optical path adjustment component 26 to reflect the reference beam to the output port 11, thus adjusting the beam projection position. Then, the reference light source 25 is turned off, the laser emitter 21 of the required wavelength is turned on and emits a laser beam. At the same time, the moving mechanism 24 is controlled to move the first reflector 23 linearly to the output optical path of the corresponding first optical path adjustment component 22, thus reflecting the laser beam and projecting it to the output port 11.
[0083] Based on some or all of the above embodiments, in some embodiments, reference is made to Figure 6 The all-in-one laser device also includes a housing 1, in which the laser emitting component, optical path mechanism, and optical path switching mechanism are disposed, and the light output port 11 is disposed on the housing 1. Specifically, the reference light source 25 is also disposed in the housing 1.
[0084] In some embodiments, the bottom plate of the housing 1 is provided with a fastener mounting position 13, and the side plate of the housing 1 is provided with a recess 12, which avoids the fastener mounting position 13. By assembling a fastener on the fastener mounting position 13, the bottom plate is mounted on the working panel, thereby fixing the laser equipment. The recess 12 can be an arc-shaped recess to make way for the fastener mounting position 13.
[0085] In some embodiments, the housing 1 is provided with at least one heat dissipation part 14, which is aligned with the end of the cooling mechanism 3. The heat dissipation part 14 can be provided at one end of the cooling mechanism 3 or at both ends of the cooling mechanism 3 to further improve the heat dissipation effect.
