Problems solved by technology

But in this way, the position of the adjusted crystal has changed again. When adjusting one degree of freedom, it will affect the other two degrees of freedom. It is always difficult to adjust the crystal to the best position and fasten it, which is very cumbersome and time-consuming.
At the same time, because the same crystal mounting base is shared, the adjustment for one crystal will affect the other crystal, and it often takes repeated debugging to achieve the effect, wasting a lot of time
The technical solution disclosed in this utility model has complex structure and cumbersome operation
Not conducive to large-scale industrial application

The frequency doubling crystal electrically controlled point shifting device has high reliability and good repeatability.

Description

technical field [0001] The invention belongs to the field of industrial lasers, in particular to a frequency-doubling crystal electronically controlled point-shifting device for solid-state lasers. Background technique [0002] Ultraviolet laser has short wavelength, small focused spot, and high photon energy. It directly destroys the molecular bonds of many non-metallic materials during material processing to achieve "cold" processing, with smooth material edges and small carbonization. [0003] To realize the reliable and stable output of high-power ultraviolet laser above 8W, it is required that the 1064nm infrared fundamental frequency laser can generate high-power basement membrane oscillation with high beam quality, and the laser crystal has as small a thermal lens and thermally induced birefringence effect as possible. At the same time, in order to achieve the best Good nonlinear polarization matching requires easy adjustment of ultraviolet nonlinear crystals and gree...
