Abstract

The invention provides a 266nm solid-state laser and a beam quality optimization method thereof, wherein the 266nm solid-state laser includes a first frequency doubling structure and a second frequency doubling structure; After the first frequency doubling structure, it is used to receive the 532nm laser beam formed by the first frequency doubling structure and convert it into a 266nm high-power ultraviolet laser beam; wherein, the second frequency doubling structure includes a quadruple frequency doubling crystal component, and the quadruple frequency doubling crystal The component is composed of a combination of the first BBO crystal, CLBO crystal and the second BBO crystal arranged in sequence along the laser exit optical path, and is used for frequency doubling conversion of the 532nm laser beam exiting along the laser exit optical path to obtain 266nm high-power ultraviolet Laser beam. Therefore, based on the 266nm solid-state laser of the present invention, under the condition that the 266nm laser power output is guaranteed, two nonlinear crystal cascading methods of BBO crystal and CLBO crystal are used to improve the output beam quality and prolong the service life of the crystal at the same time and reduced laser cost.

Description

Technical field [0001] The present invention relates to the field of laser light, and more particularly to a 266 nM solid laser based on nonlinear crystals and a beam quality optimization method thereof. Background technique [0002] At present, as an important method of obtaining high power ultraviolet lasers, multiplier conversion technology has received more and more attention. Among them, the laser power and beam mass based on the crystal is closely related to the material, structure, and corresponding characteristics of the crystal itself. Typically, in frequency conversion techniques, the nonlinear crystals typically employed are primarily BBO and CLBO crystals for the purpose of reaching 532 nm to 266 nm laser conversion. BBO crystals and CLBO crystals have a high transmittance for 532 nm and 266 nm. Among them, BBO crystals have low cost relative to CLBO crystals, high effective nonlinear coefficients, low hroemption properties, better chemical stability, and matching tem...
