Description

Technical Field

[0001] The utility model relates to the technical field related to high-power laser heads, in particular to a high-power laser head stable output device. Background Art

[0002] The output stability of the laser head of a traditional high-power laser is often disturbed by a variety of factors, such as changes in ambient temperature, thermal distortion of optical components, and nonlinear effects of optical materials. These factors lead to fluctuations and instability in the laser output, which affects the reliability and performance of the laser in practical applications. By combining new optical materials and designing a more efficient cooling system, the temperature of optical components can be effectively reduced, and the fluctuation of laser output caused by thermal distortion can be reduced. At present, high-power lasers with water-cooled structures have a relatively stable output. However, although the water-cooled structure can control the temperature of the laser and provide a certain degree of stability, it cannot solve all factors that may affect the stability of the laser output. In addition, some parameters of the laser may change slightly each time the laser is used. These changes may be caused by factors such as the performance attenuation of the laser, changes in environmental conditions, and thermal expansion of optical components. The output of the laser will change each time it is used, so there is an urgent need for a device to adjust the laser output in time to ensure the stability of the laser head output.
