Solid-state tunable deep-ultraviolet laser system from 198 to 300 nm

Abstract

An all-solid-state laser system continuously tunable from 198 to 300 nm is developed for the first time to our knowledge. This tunable UV laser system consists of a Ti:sapphire laser, a Nd:YAG laser, and the nonlinear mixing enclosures and has relatively high average output of more than 8 mW and a narrow bandwidth of the order of 0.1 nm over the entire range. Typical characteristics of this laser are presented.
