[0020] As Figure 1 shown, the automatic monitoring quick release high-power beam combining laser provided by the embodiment of the utility model comprises a multi-channel laser module, a laser beam combining module, a beam splitter 12 and an optical fiber coupling module, wherein:

[0021] The multi-channel laser module comprises a plurality of monochromatic lasers, and the monochromatic lasers are used to output single-wavelength single-beam lasers. The number of channels of the monochromatic lasers is greater than or equal to 2, for example, the monochromatic lasers can be three as shown in Figure 1 , a first monochromatic laser 11, a second monochromatic laser 11 and a third monochromatic laser 11, and can also be determined according to application requirements. The output end of each channel of the monochromatic laser is provided with a laser beam combining module, and each laser beam combining module is used to receive the single-beam laser output by the corresponding channel of the monochromatic laser and control the spatial positioning of the single-beam laser, so as to ensure that the single-beam lasers of each channel can converge into a single beam and output a combined beam laser.

[0022] In combination with Figure 1The multi-channel laser module includes a first monochromatic laser 11, and a corresponding laser beam combining module of the first monochromatic laser 11 is a mirror 14. The mirror 14 is used to control the propagation direction of the single laser beam output by the first monochromatic laser 11 to produce a first preset angle of inclination, and then reflect the output first monochromatic laser beam. The first preset angle is determined according to the installation adjustment frame of a general mirror and the installation adjustment frame of a dichroic mirror, such as Thorlabs POLARIS-K1E, KM100, etc., which can adjust the angle range of ±4°.

[0023] The multi-channel laser module further includes a second monochromatic laser 11, and a corresponding laser beam combining module of the second monochromatic laser 11 is a first dichroic mirror 15. The first dichroic mirror 15 is used to transmit the first monochromatic laser beam, and is further used to control the propagation direction of the single laser beam output by the second monochromatic laser 11 to produce a second preset angle of inclination, and then reflect the output two-color laser beam. The second preset angle has the same range as the first preset angle.

[0024] The multi-channel laser module further includes a third monochromatic laser 11, and a corresponding laser beam combining module of the third monochromatic laser 11 is a second dichroic mirror 16. The second dichroic mirror 16 is used to transmit the two-color laser beam, and is further used to control the propagation direction of the single laser beam output by the third monochromatic laser 11 to produce a second preset angle of inclination, and then reflect the output two-color laser beam.

[0025] Of course, the above embodiment is for the case where the number of monochromatic lasers is 3. In the case where the number of monochromatic lasers is other, for example, 4, the function of the second dichroic mirror 16 is the same as that of the first dichroic mirror 15 in the above embodiment. The last dichroic mirror, that is, the fourth dichroic mirror, has the same function as the second dichroic mirror 16 in the above embodiment, and so on.

[0026] The beam splitter 12 and the fiber coupling module are arranged in sequence on the propagation path of the combined laser beam. The combined laser beam is split into two beams by the beam splitter 12, one of which is input to the fiber coupling module, and the other of which is used to input the four-quadrant photodetector 13. The four-quadrant photodetector is used to calculate the centroid position of the light beam falling on the detector according to four light current signals, and to monitor the offset of the centroid in real time.

[0027] In one embodiment, the fiber coupling module includes a coupler 17 and an optical fiber 18. The combined laser beam is coupled into the optical fiber 18 through the coupler 17 and then output.

[0028] In one embodiment, the multi-channel laser module further comprises a parallel plate 19 arranged between the mirror 14 and the output of the monochromatic laser 11, and between the dichroic mirrors 15, 16 and the output of the monochromatic laser 11, for adjusting the propagation angle and position of the monochromatic laser light emitted from the monochromatic laser 11 to maximize the light energy coupled into the optical fiber 18 by the coupler 17. The parallel plate 19 can be implemented by existing products such as Thorlabs WG11050, WG41050-UV, etc., which can serve as an optical window sheet by itself. As shown in Figure 1 the parallel plate 19 is arranged between the mirror 14 and the output of the first monochromatic laser 11, between the first dichroic mirror 15 and the second monochromatic laser 11, and between the second dichroic mirror 16 and the output of the third monochromatic laser 11, for adjusting the propagation angle and position of the laser light emitted from the monochromatic laser to maximize the light energy coupled into the optical fiber by the coupler.

[0029] In one embodiment, as shown in Figures 2-4 the multi-channel laser module comprises a multi-channel laser generation module 20 and a plurality of monochromatic lasers 11 arranged in the multi-channel laser generation module 20, each monochromatic laser 11 is installed into a reserved laser output channel in the multi-channel laser generation module 20 through a channel assembly 10, and a quick-release structure is arranged between the mounting base 9 of the monochromatic laser 11 and the channel assembly 10.

[0030] The quick-release structure comprises a first magnetic assembly, a second magnetic assembly, and a switch assembly. The first magnetic assembly is fixed to the mounting base 9, the second magnetic assembly is fixed to the channel mounting surface 10a of the channel assembly 10, and the relative positions of the first magnetic assembly and the second magnetic assembly are switched between a first position and a second position under the control of the switch assembly. In the first position, the first magnetic assembly and the second magnetic assembly provide a magnetic attraction force that can fixedly connect the monochromatic laser 11 to the channel assembly 10, and in the second position, the magnetic attraction force between the first magnetic assembly and the second magnetic assembly is greatly reduced, so that the monochromatic laser 11 is separated from the channel assembly 10.

[0031] In one embodiment, the first magnetic assembly comprises three first magnetic sheets 2 arranged at intervals, and the second magnetic assembly comprises a rotating base 5, which comprises three second magnetic sheets 6 corresponding to the number and interval of the first magnetic sheets 2. In the first position, the first magnetic sheets 2 are opposite to the second magnetic sheets 6, generating magnetic attraction. In the second position, the first magnetic sheets 2 are misaligned with the second magnetic sheets 6, so that the three magnetic sheet positions no longer correspond, thereby removing most of the magnetic attraction. In this non-magnetic state, it is easy to remove the monochromatic laser from the laser base. Those skilled in the art can know that the larger the volume, the larger the contact area, and the stronger the magnetic attraction. Considering the size and weight of the monochromatic laser, appropriate sizes are selected, for example, the size of the first magnetic sheet 2 and the second magnetic sheet 6 is: diameter 6mm, thickness 5mm.

[0032] In one embodiment, the first magnetic assembly further comprises a magnetic column pair 1, which is composed of two magnetic columns arranged close to the outer edge of the first magnetic sheet 2 to form an outer surrounding structure of the first magnetic sheet 2. The second magnetic assembly further comprises a magnetic bead 4 corresponding to the number and interval of the magnetic column pair 1. In the first position and the second position, the magnetic column pair 1 and the magnetic bead 4 remain opposite, generating magnetic attraction. Of course, the smaller the contact area, the smaller the magnetic attraction. Considering the size and weight of the monochromatic laser, appropriate sizes are selected, for example, the diameter of the magnetic column is 3mm, the length is 6mm, and the diameter of the magnetic bead 4 is 5mm, which has magnetic attraction.

[0033] In one embodiment, the number of the first magnetic sheet 2, the second magnetic sheet 6, the magnetic column pair 1 and the magnetic bead 4 is three, arranged in the form of the vertices of an equilateral triangle. Each first magnetic sheet 2 is arranged outside a magnetic column pair 1. In the first position, the magnetic column pair 1 and the magnetic bead 4 remain opposite, and the magnetic attraction of one magnetic column pair 1 fixes one magnetic bead 4. Through the three magnetic column pairs, the positions of the three magnetic beads can be uniquely determined. In the first position, the first magnetic sheet 2 is opposite to the second magnetic sheet 6, and the magnetic attraction of the first magnetic sheet 2 fixes the second magnetic sheet 6. Through these groups of magnetic attraction, the monochromatic laser is fixed. In the second position, the magnetic column pair 1 is opposite to the magnetic bead 4, and the first magnetic sheet 2 is misaligned with the second magnetic sheet 6, so that the three magnetic sheet positions no longer correspond, thereby removing most of the magnetic attraction. In this state, it is easy to remove the monochromatic laser from the laser base.

[0034] In one embodiment, each rotating base 5 is arranged outside a switch assembly. "Outside" can be understood as the direction away from the center of the rotating base 5. The switch assembly is used to control the rotation of the rotating base 5, so as to place the relative positions of the second magnetic sheet 6 on the rotating base 5 and the first magnetic sheet 2 in a relative state or a misaligned state. In the relative state, the second magnetic sheet 6 and the first magnetic sheet 2 generate magnetic attraction. In the misaligned state, the second magnetic sheet 6 and the first magnetic sheet 2 are in a non-magnetic state. By removing most of the magnetic attraction, it is convenient to remove the monochromatic laser from the combined laser.

[0035] In one embodiment, as shown in FIG. 6, the switch assembly comprises a switch 7 and a switch button 8. The switch 7 is arranged outside the rotating base 5, and the switch button 8 is arranged on the rotating base 5. When the switch button 8 is pressed, the switch 7 is turned on, and the rotating base 5 rotates to the first position. When the switch button 8 is not pressed, the switch 7 is turned off, and the rotating base 5 rotates to the second position. Figure 3As shown, the channel assembly 10 is a plate-like structure with a thickness, the side where the thickness direction and the width direction are located is provided with a slot 7 along the length direction, the side where the length direction and the width direction are located is the channel mounting surface 10a, the channel mounting surface 10a is provided with the first assembly hole of the rotating base 5 and the second assembly hole of the second magnetic sheet 6 along the thickness direction, and the first assembly hole is through the slot 7.

[0036] The switch assembly includes a dial column 8, one end of the dial column 8 extends into the slot 7 and is fixedly connected with the rotating base 5 assembled in the first assembly hole, the other end of the dial column 8 is located outside the slot 7 and can rotate together with the rotating base 5 under the control of external force, thereby changing the relative position of the second magnetic sheet 6 and the first magnetic sheet 2. Figure 4 And Figure 5a 、 Figure 5b 、 Figure 5c As shown, A is the relative position of the second magnetic sheet 6 and the first magnetic sheet 2 in the relative state, and B is the relative position of the second magnetic sheet 6 and the first magnetic sheet 2 in the staggered state.

[0037] In the above embodiments, the quick-release structure fixes the single-color laser on the laser base, and the laser base can be adsorbed to the corresponding position in the beam combining laser, and is fixed by the strong attraction between the magnetic sheet, the magnetic bead and the magnetic column. By sliding the dial column, the magnetic attraction can be released or added, which facilitates the disassembly and installation of the single-color laser. For the fiber output beam combining laser composed of multiple single-color spatial light lasers, the single-color lasers can be flexibly disassembled and replaced according to different wavelength requirements. In addition, in the actual application process, the deviation of the spatial light can be monitored in real time, and the reduction of the coupling efficiency can be identified in time, so that corresponding adjustment and optimization can be carried out. This design not only improves the flexibility of the system, but also ensures the performance stability of the laser in different application scenarios.

[0038] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Those skilled in the art should understand that the technical solutions described in the above embodiments can be modified, or some technical features can be replaced by equivalents; these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
