Problems solved by technology

[0006] In the prior art, it can be solved by changing the length of the mirror cavity, such as increasing the length of the mirror cavity to increase the longitudinal modulus, or shortening the length of the mirror cavity to reduce the longitudinal modulus. However, the above-mentioned long mirror cavity method and short mirror The cavity method too much limits the mirror cavity length of the laser, which brings many restrictions to the design of the laser; in the prior art, a self-stabilizing system can also be used to control the output, but this method increases the production cost of the laser

Abstract

A device for generating laser and a method thereof are provided. The device for generating laser includes an input coupling mirror (102), an output coupling mirror (106), a first cavity mirror (104), a laser crystal (103), and a wavelength converting unit. The first cavity mirror (104), disposed between the laser crystal (103) and the wavelength converting unit, is for partially transmitting a fundamental frequency light. The input coupling mirror (102) and the output coupling mirror (106) are for highly reflecting the fundamental frequency light.

Description

technical field [0001] The invention relates to laser technology, in particular to a laser processing device, method and laser display light source. Background technique [0002] Laser has the characteristics of good monochromaticity, strong directionality and high brightness. The core of laser technology is lasers. There are many types of lasers, which can be classified according to different methods such as working substances and working wavelengths. [0003] Today, laser technology is starting to find applications in television, pico projection, business and entertainment systems. The laser frequency doubling technology greatly expands the existing laser frequency, not only realizes the laser output in the visible light band, but also realizes the laser output in the ultraviolet band by using triple frequency and quadruple frequency technology. Laser display technology is one of the main application directions of lasers. It has the characteristics of large color gamut a...
