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

Abstract

The invention discloses an ultraviolet laser. A frequency tripling crystal is fixed on a frequency tripling crystal base; three rotational degrees of freedom of the frequency tripling crystal can be adjusted through the frequency tripling crystal base; a frequency doubling crystal is fixed on a frequency doubling crystal base; and three rotational degrees of freedom of the frequency doubling crystal can be adjusted through the frequency doubling crystal base. Separate adjustment of the frequency tripling crystal and the frequency doubling crystal is realized, and mutual influences are avoided. The three rotational degrees of freedom of the frequency doubling crystal and the frequency tripling crystal can be adjusted independently through the frequency tripling crystal base and the frequency doubling crystal base, and adjustment of the degrees of freedom of the frequency doubling crystal and adjustment of the degrees of freedom of the frequency tripling crystal do not influence each other. Through adoption of the ultraviolet laser, rapid and convenient adjustment is realized, and higher efficiency and a better adjustment effect are achieved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to an ultraviolet laser. 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. The diode-pumped 355nm ultraviolet laser has many advantages such as good beam quality, high efficiency, good power stability, high reliability, convenient use, and small size. Wide range of applications. [0003] The diode-pumped high-power (>8W) 355nm ultraviolet laser is made by doubling the frequency of the fundamental frequency infrared laser with a wavelength of 1064nm inside or outside the cavity, and then part of the fundamental frequency light is corresponding to the 532nm green light generated by the double frequency. The way triple frequency (ie sum freq...
