Abstract

An ultraviolet solid-state laser with non-linear crystal relates to the art of designing solid-state laser. The non-liner laser crystal with doping rare earth ion produces base wave and frequency doubling laser, the base wave and frequency doubling laser are mixed through the non-linear crystal and produce the ultraviolet band solid laser.

Description

technical field [0001] The invention relates to the field of solid-state laser device design. Background technique [0002] Ultraviolet lasers can be used in atomic and molecular spectroscopy, biology, isotope separation, laser chemistry, optical data storage, etc., and are widely used in microelectronics, laser processing, scientific research and other fields. Although excimer lasers can directly output ultraviolet laser light, such lasers use corrosive gases, have high-pressure gas discharges, require regular maintenance, and are bulky. Therefore, generating near-infrared fundamental wave laser from a relatively mature semiconductor laser pumped laser crystal, and then converting frequency through nonlinear optics is a better means to successfully obtain ultraviolet laser, such as 1064nm Nd-doped 3+ The solid-state fundamental wave laser was first tested by KTiOPO 4 (KTP) crystal frequency doubling to obtain 532nm, and then through LiB 3 o 4 (LBO), β-BaB 2 o 4 (BBO),...
