Problems solved by technology

[0003] The existing 266nm laser mainly generates nanosecond fundamental frequency light through active Q-switching, and then generates 266nm nanosecond laser through two consecutive frequency doublings. It is difficult to generate picosecond 266nm laser; and the existing 266nm laser pump source and resonant cavity A pump coupling system is used between them, the laser is large in size and complex in structure; due to the walk-off effect of the quadrupling frequency crystal, the beam quality is poor, the frequency doubling efficiency is low and the service life is short

Abstract

The invention provides a 266nm pulse solid laser which is free of a pumping coupling system, small in size and simple in structure; picosecond pulse width fundamental frequency light can be output in a four-section bonding crystal passive Q-switching mode, and then picosecond 266nm laser can be output; the frequency doubling conversion efficiency can be improved by focusing 1064nm laser to perform frequency doubling and collimating 532nm laser to perform frequency quadruplicating; the quadruplicated frequency crystal adopts a non-critical phase matching high-temperature working mode, so that the quality of a 266nm laser beam is greatly improved, and deliquescence of the CLBO crystal is effectively prevented; the shift point design of the quadruplicated frequency crystal can effectively prolong the service life of the laser.

Description

technical field [0001] The invention relates to the technical field of solid lasers, in particular to a 266nm pulsed solid laser. Background technique [0002] The 266nm laser has a short wavelength and high single-photon energy, and can achieve a smaller focused spot. It is widely used in biological detection, spectral analysis, medical treatment, precision micro-processing, aviation and other fields. High-energy and high-repetition-frequency 266nm laser is mainly generated by Q-switching to generate pulsed fundamental frequency 1064nm laser, then amplifies the fundamental frequency light through an amplifier, and then generates it through two consecutive frequency doublings. [0003] The existing 266nm laser mainly generates nanosecond fundamental frequency light through active Q-switching, and then generates 266nm nanosecond laser after two consecutive frequency doublings. It is difficult to generate picosecond 266nm laser; and the existing 266nm laser pump source and res...
