[0036] like Figures 1 to 6As shown, an embodiment of the present application provides an adjustment device for a solid-state laser, comprising a housing 1, an adjustment seat 4, a Q-switched switch 5, an adjustment member 6 and an output membrane 7, wherein the housing 1 is provided with a light outlet, the adjustment seat 4 is provided with a fixing portion 41, the fixing portion 41 has a first adjustment hole 411 and a receiving groove 412, the adjustment seat 4 is fixed to the housing 1, the Q-switched switch 5 is provided with a second adjustment hole 522 and a protrusion 523, the protrusion 523 is located in the receiving groove 412, the adjustment member 6 is passed through the second adjustment hole 522 and the first adjustment hole 411, wherein the adjustment member 6 adjusts the depth of the penetration into the first adjustment hole 411 so that the protrusion 523 located in the receiving groove 412 rotates, and the output membrane 7 is fixed to the side of the Q-switched switch 5 close to the light outlet.

[0037] Specifically, a resonant cavity 11 is provided in the housing 1, and the solid-state laser is provided with a light-emitting component 2. The light-emitting component 2 is fixed to the housing 1. The light-emitting component 21 of the light-emitting component 2 emits light, which forms a laser after passing through the working crystal 3 in the resonant cavity 11, and the laser is finally emitted from the light outlet. For example, the light-emitting component 21 is a pump source, and the Q-switched switch 5 tunes the high-power laser to generate the required laser pulses. The Q-switched switch 5 is arranged in the housing 1 and works in conjunction with the light-emitting component 2 to achieve laser tuning. Through the second adjustment hole 522, the protrusion 523 and the adjustment component 6, the Q-switched switch 5 is rotated in the receiving groove 412, thereby fine-tuning the laser to meet the use requirements. The output film 7 is made of a high-transmittance material, such as an anti-reflection film, and the output film 7 is fixed to the side of the Q-switched switch 5 close to the light outlet 12.

[0038] The light-emitting assembly 2 is fixed to the housing 1. Light emitted by the pump source enters the resonant cavity 11. The adjustment base 4 is fixed to the housing 1. The first adjustment hole 411 is penetrated by the adjustment member 6. The protrusion 523 is located within the receiving groove 412. By adjusting the depth of the adjustment member 6 into the first adjustment hole 411, the protrusion 523 rotates to adjust the position of the Q-switch 5. By adjusting the position of the adjustment member 6, the laser output is adjusted and controlled. In particular, the contours of the receiving groove 412 and the protrusion 523 are both hemispherical.

[0039] Since the contours of the receiving groove 412 and the protrusion 523 are both hemispherical, it helps to ensure that the Q-switched switch 5 is in close contact with the protrusion 523 during installation, which is conducive to rotation and facilitates adjustment of the laser emission requirements.

[0040] The adjusting member 6 is passed through the second adjusting hole 522 and the first adjusting hole 411. For example, the adjusting member 6 is a screw, and the adjusting member 6 is threadedly connected to the fixing part 41. The adjusting member 6 is threadedly connected to the fixing part 41, which is conducive to adjusting the position of the Q-switched switch 5 in the solid-state laser and also fixes the Q-switched switch 5.

[0041] The protrusion located in the receiving groove 412 is rotated by the adjusting member 6, thereby adjusting the Q-switched switch 5, and accurately controlling the output characteristics of the laser.

[0042] In some embodiments, the Q-switched switch 5 includes a Q-switched crystal 51 and a mounting member 52 . The mounting member 52 is provided with a mounting groove 521 , a second adjustment hole 522 and a protrusion 523 . The Q-switched crystal 51 is located in the mounting groove 521 .

[0043] Specifically, the Q-switched crystal 51 is made of Nd:YAG (neodymium yttrium aluminum garnet) or Nd:YLF (neodymium yttrium lithium fluoride). A mounting groove 521 is provided within the mounting member 52, which accommodates a portion of the Q-switched switch 5. A protrusion 523 is positioned within the receiving groove 412 of the adjustment base 4. The contact position between the protrusion 523 and the mounting groove 521 is adjusted using the adjustment member 6. For example, by adjusting the depth of the adjustment member 6 penetrating into the second adjustment hole 522, the protrusion 523 is rotated, thereby adjusting the position of the Q-switched crystal 51, maintaining the laser in optimal operating condition, and thus achieving laser output control.

[0044] It should be understood that the light emitting element 21 (pump source) emits pump light, which forms an optical path through the working crystal 3, resonant cavity 11, and multiple emission mirrors (not shown), enhancing the resonance of the laser. The working crystal 3 effectively converts light into the desired laser light. The Q-switched crystal 51 is used to modulate the width of the laser pulse to achieve ultrashort pulse laser output. The Q-switched crystal 51 tunes the high-power laser to produce the desired laser pulses. Tuning refers to changing the characteristics or parameters of certain components within the laser to change the output wavelength of the laser.

[0045] By adjusting the depth of the adjustment member 6 inserted into the first adjustment hole 411, the position of the protrusion 523 can be precisely controlled, thereby precisely controlling the position of the Q-switched crystal 51, thereby ensuring that the laser output characteristics are more in line with the requirements. The mounting groove 521 of the mounting member 52 allows the Q-switched crystal 51 to be securely mounted in the laser, improving the structural stability and reliability of the entire laser.

[0046] In some embodiments, the mounting member 52 is provided with a limiting ring 524 . The limiting ring 524 has a central hole P. The limiting ring 524 is used for limiting the contact with the Q-switched crystal 51 .

[0047] Specifically, the mounting member 52 is provided with a retaining ring 524 having a center hole P that communicates with the mounting slot 521. The shape and size of the retaining ring 524 match those of the Q-switching crystal 51. For example, the Q-switching crystal 51 is placed in the mounting slot 521 so that it faces the center hole P of the retaining ring 524. The output film 7 is fixed to the Q-switching crystal 51, and the retaining ring 524 and the Q-switching crystal 51 abut against each other. The output film 7 is attached to the side of the Q-switching crystal 51 closest to the light output port.

[0048] In some embodiments, the fixing portion 41 defines a through hole 413 , and the through hole 413 is coaxially arranged with the central hole P.

[0049] Specifically, through-hole 413 is located on the fixing portion 41, coaxially with the center hole P. The Q-switched crystal 51 is placed within the mounting groove 521, abutting against the retaining ring 524. With through-hole 413 facing the center hole P, this facilitates laser emission. The fixing portion 41, retaining ring 524, and adjusting member 6 ensure that the Q-switched crystal 51 maintains the required position within the resonant cavity 11 for precise emission, thus meeting laser output requirements.

[0050] In some embodiments, the mounting member 52 includes a connecting portion 525, a second adjustment hole 522 located on the connecting portion 525, and an integrally formed connection portion 525, a retaining ring 524, and a protrusion 523. This integral formation of the connecting portion 525, the retaining ring 524, and the protrusion 523 ensures the structural stability of the entire mounting member 52. The second adjustment hole 522 is located on the connecting portion 525, and the adjusting member 6 passes through the second adjustment hole 522 for adjustment and fixation. The position and size of the second adjustment hole 522 should take into account the rotation requirements of the Q-switched switch 5, ensuring that the adjusting member 6 can effectively adjust the Q-switched switch 5 and also secure the Q-switched switch 5 to the fixing portion 41. The retaining ring 524 is connected to the connecting portion 525 and is used to limit and abut the Q-switched crystal 51. The protrusion 523 is located on the connecting portion 525 and engages with the receiving groove 412. The connecting portion 525 , the limiting ring platform 524 and the protruding portion 523 are integrally formed, which simplifies the structure of the mounting member 52 , reduces the manufacturing cost of the laser, and improves the structural strength of the mounting member 52 .

[0051] In some embodiments, the number of the first adjustment holes 411 and the number of the second adjustment holes 522 are both plural, and the plurality of first adjustment holes 411 and the plurality of second adjustment holes 522 are arranged in an interval shape.

[0052] Specifically, the first adjustment holes 411 and the second adjustment holes 522 are located on the fixing portion 41 and the mounting member 52, respectively, and are each provided in a plurality. The plurality of first adjustment holes 411 and the plurality of second adjustment holes 522 are arranged in a spaced pattern. For example, there are three first adjustment holes 411 and three second adjustment holes 522, with the three first adjustment holes 411 evenly spaced about the axis of the through-hole 413, and the three second adjustment holes 522 evenly spaced about the axis of the center hole P. By providing a plurality of first adjustment holes 411 and a plurality of second adjustment holes 522, and by providing these adjustment holes in a spaced pattern, it is easier to adjust the position of the Q-switched switch 5, thereby improving adjustment flexibility.

[0053] In some embodiments, the adjusting member 6 is a screw or a bolt, and the adjusting member 6 , the second adjusting hole 522 and the first adjusting hole 411 are arranged in a group.

[0054] Specifically, the adjusting member 6 is a screw or a bolt, and the adjusting member 6 is screwed into the second adjusting hole 522 and the first adjusting hole 411, thereby adjusting the position of the Q-switching switch 5. The adjusting member 6, the second adjusting hole 522 and the first adjusting hole 411 are arranged in a group, which represents a one-to-one correspondence between the adjusting member 6, the second adjusting hole 522 and the first adjusting hole 411. The adjusting member 6 is provided with the first adjusting hole 411 and the second adjusting hole 522, so that the adjusting member 6 can adjust the Q-switching switch 5. After the position of the adjusting member 6 is adjusted to meet the requirements of laser use, the limiting ring 524 limits the contact with the Q-switching crystal 51. Under the action of the fixing part 41, the mounting part 52 and the adjusting member 6, the group arrangement of the adjusting member 6, the second adjusting hole 522 and the first adjusting hole 411 is utilized to achieve precise adjustment and fixation of the Q-switching switch 51, thereby achieving laser output wave regulation.
