Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to a laser crystal adjustment device. Background Technology

[0002] In laser applications, crystals are generally used as the laser medium. For a laser to output the required wavelength of energy, the crystal needs to maintain a stable state. Crystals can provide good laser feedback and amplification, and also offer good optical properties during processing.

[0003] When the wavelength energy of a laser decreases, the temperature and angle of the crystal need to be adjusted. In existing technology, the crystal is typically mounted inside the laser using a standard crystal mount. When adjusting the crystal's temperature and angle, the laser must be disassembled for manual adjustment; adjustment cannot be performed externally. This makes crystal adjustment inconvenient and inefficient, and there is a lack of a fast and accurate device for automatically adjusting the crystal's temperature and angle. Utility Model Content

[0004] This invention primarily addresses the technical problem that existing technologies require disassembling the laser for manual adjustment when adjusting the temperature and angle of a crystal, making crystal adjustment inconvenient and inefficient. The invention proposes a laser crystal adjustment device that allows for external control of the micro-angle adjustment process, enabling automatic adjustment without disassembling the laser. This simplifies manual operation and improves adjustment efficiency.

[0005] This utility model provides a laser crystal adjustment device, including: a base, a crystal adjustment frame, a servo motor, and a crystal fixing frame;

[0006] The crystal adjustment frame includes: an adjustment frame fixing part, a first adjustment frame clamping part, and a second adjustment frame clamping part;

[0007] An adjustment frame fixing part is fixedly provided on the base; a servo motor is provided on one side of the adjustment frame fixing part, and a first adjustment frame clamping part is movably provided on the other side; the first adjustment frame clamping part has a protruding structure, which passes through the adjustment frame fixing part and is fixedly connected to the output shaft of the servo motor;

[0008] The crystal holder is fixed between the first adjustment bracket clamping part and the second adjustment bracket clamping part; the crystal is installed in the crystal holder.

[0009] Preferably, a heating device and a temperature probe are provided at the bottom of the crystal holder.

[0010] Preferably, an L-shaped servo motor cover plate is fixedly connected to the adjusting frame fixing part;

[0011] The servo motor cover plate is fixedly connected to the servo motor.

[0012] Preferably, the first adjustment frame clamping part and the second adjustment frame clamping part are fixed by bolts.

[0013] Preferably, the crystal holder is cylindrical.

[0014] This invention provides a laser crystal adjustment device with a simple structure, high accuracy, space-saving design, convenient operation, high reliability, and precise adjustment. It can monitor crystal temperature and adjust crystal angle in real time. The micro-angle adjustment process of the crystal can be controlled externally to the laser, achieving automatic adjustment without disassembling the laser or requiring manual adjustment. This simplifies manual operation and improves adjustment efficiency. A temperature probe on the crystal holder monitors the crystal's operating temperature in real time. When the temperature is below a threshold range, the heating device automatically starts to raise the temperature; when the temperature is above the threshold range, the heating device shuts off. This invention achieves automatic crystal temperature adjustment. Attached Figure Description

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0022] like Figure 1-4 As shown in the figure, a laser crystal adjustment device provided in this embodiment of the present invention includes: a base 7, a crystal adjustment frame 2, a servo motor 3, and a crystal fixing frame 4.

[0023] like Figure 5 As shown, the crystal adjustment frame 2 includes: an adjustment frame fixing part 201, a first adjustment frame clamping part 202, and a second adjustment frame clamping part 203.

[0024] An adjustment bracket fixing part 201 is fixedly provided on the base 7; threaded holes are provided on the base 7 and the adjustment bracket fixing part 201 respectively, and the base 7 and the adjustment bracket fixing part 201 are fixed by bolts, so that the adjustment bracket fixing part 201 is fixed on the base 7.

[0025] A servo motor 3 is mounted on one side of the adjusting frame fixing part 201, and a first adjusting frame clamping part 202 is movably mounted on the other side. The first adjusting frame clamping part 202 has a protruding structure 204, which passes through the adjusting frame fixing part 201 and is fixedly connected to the output shaft of the servo motor 3. Rotation of the output shaft of the servo motor 3 can drive the first adjusting frame clamping part 202 to rotate.

[0026] The first adjustment frame clamping part 202 and the second adjustment frame clamping part 203 are fixed together by bolts. A clamping space is formed between the first adjustment frame clamping part 202 and the second adjustment frame clamping part 203. The crystal fixing frame 4 is fixed between the first adjustment frame clamping part 202 and the second adjustment frame clamping part 203, so that the crystal fixing frame 4 is fixed by the crystal adjustment frame 2. The rotation of the output shaft of the servo motor 3 can drive the first adjustment frame clamping part 202, the second adjustment frame clamping part 203 and the crystal fixing frame 4 to rotate.

[0027] The crystal holder 4 is cylindrical. A crystal 8 is installed in the crystal holder 4. A heating device 5 and a temperature probe 6 are located at the bottom of the crystal holder 4. Specifically, the crystal holder 4 has pre-drilled threaded holes through which the temperature probe 6 and the heating device 5 are fixed.

[0028] An L-shaped servo motor cover plate 1 is fixedly connected to the adjusting bracket fixing part 201; the servo motor cover plate 1 is fixedly connected to the servo motor 3. Specifically, the adjusting bracket fixing part 201 and the servo motor cover plate 1 have threaded holes corresponding to their horizontal surfaces, and are fixed by bolts. The servo motor cover plate 1 has servo motor mounting holes on its vertical surface, and the body of the servo motor 3 is fixed to the vertical surface of the servo motor cover plate 1 by bolts.

[0029] The working principle of a laser crystal adjustment device provided in this embodiment of the utility model is as follows:

[0030] The output shaft of the servo motor 3 rotates, causing the first adjustment bracket clamping part 202 and the second adjustment bracket clamping part 203 to rotate, which in turn drives the crystal fixing bracket 4 to perform micro-angle adjustment, realizing automatic angle adjustment of the crystal 8, achieving a resolution adjustment of 0.1°. This invention allows for external control of the micro-angle adjustment process of the crystal 8, achieving automatic adjustment without disassembling the laser, making operation convenient and improving adjustment efficiency. Dynamic optimization ensures the crystal 8 is in the optimal alignment state, thereby maximizing energy output and improving the laser's conversion efficiency and operational stability.

[0031] Temperature probe 2 on crystal holder 4 monitors the operating temperature of crystal 8 in real time. When the temperature is below the temperature threshold range, heating device 5 automatically starts to raise the temperature; when the temperature is above the temperature threshold range, heating device 5 shuts off. This invention achieves automatic crystal temperature regulation. The laser crystal adjustment device can achieve a temperature control accuracy of ±0.01℃, ensuring that crystal 8 is always within the optimal operating temperature range and avoiding laser output instability caused by temperature fluctuations. The optimal operating temperature threshold range for the crystal is 30-50 degrees Celsius, with an accuracy control of 0.01 degrees Celsius.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
