Abstract

The present invention provides an automatic laser transverse film stabilizing device. The automatic laser transverse film stabilizing device comprises an output coupler, temperature sensors and an output coupler angle adjuster; the output coupler is provided with the plurality of temperature sensors which equally divide the output coupler and measures the temperature of the corresponding positions of the output coupler; the temperature sensors are in electrical connection with the output coupler angle adjuster and feeds back measured data to the output coupler angle adjuster; and the output coupler angle adjuster adjusts the angle of the output coupler, so that temperature on the output coupler can be uniform.

Description

technical field [0001] The invention relates specifically to an automatic laser transverse film stabilization device which measures the spatial temperature imbalance in laser optics and uses this signal in a feedback loop to drive an automatic actuator to adjust the optical alignment. Background technique [0002] The alignment of the laser resonator is changing with the temperature of the optomechanical components due to reasons such as overall temperature changes (differential expansion of different material parts), partial absorption of the laser beam (through diffraction effects or bulk absorption of transmissive components), etc. Change to change. The resulting small geometric deformations cause misalignment between the mechanical and optical system axes. There are thus variations in mode symmetry, focusing properties and final processing properties. [0003] Furthermore, since the main contribution to these local temperature changes is the absorption of optical power...
