Abstract

The present invention provides an intracavity frequency doubling enhanced laser. The laser comprises a first reflector, an SHG characteristic crystal, a THG characteristic crystal, a second reflector and a third reflector; the second reflector is configured to reflect the first frequency doubling light and the second frequency doubling light propagated in the THG characteristic crystal, the first frequency doubling light and the second frequency doubling light are reflected on a Brewster angle plane to the interior of the THG characteristic crystal, and the frequency doubling light to be reflected of the THG characteristic crystal is transmitted out; the third reflector is configured to reflect the first frequency doubling light and the second frequency doubling light propagated in the THG characteristic crystal, the first frequency doubling light and the second frequency doubling light are reflected on the Brewster angle plane, and the frequency doubling light to be reflected of the THG characteristic crystal is transmitted out; and the frequency doubling light to be used for refraction and the frequency doubling light to be used for reflection is recycled in the light path reversibility mode to the THG characteristic crystal for sum frequency, the frequency doubling light which fully employs the intracavity frequency doubling of the ultraviolet laser is recycled to reduce the invalid loss of the laser so as to maximize the sum frequency efficiency, and the recycled frequency doubling light can perform multi-time sum frequency so as to increase the power output of the ultraviolet light.

Description

technical field [0001] The invention belongs to the field of lasers, in particular to an intracavity frequency-doubling enhanced ultraviolet laser. Background technique [0002] Ultraviolet lasers are widely used in the field of industrial micro-processing, such as marking, drilling, scribing, welding, and cutting of industrial parts, as well as micro-processing of medical devices, packaging of electronic components, and three-dimensional molding of micro components . In addition, it has broad application prospects in microelectronics, spectral analysis, optical data storage, optical disc control, atmospheric detection, photochemistry, photobiology, space optical communication, laser-induced material atomic fluorescence and ultraviolet absorption, and medical treatment. The core of realizing the laser is mainly the laser working substance in the laser that can realize the inversion of the number of particles, that is, the working substance containing the metastable energy l...
