A 380-mW 7-MHz cerium LiLuF laser pumped by the frequency doubledyellow output of a copper-vapor-laser

摘要

We report a high average power Ce:LiLuF laser pumped by the secondnharmonic of the yellow output from a copper vapor laser. This ceriumnlaser yielded up to 380 mW at a pulse repetition frequency of 7 kHz atnthe peak lasing wavelength of 309.5 nm, with a slope efficiency of 50%.nIn addition, single prism tunability was obtained from 305.5 to 316 nmnand from 322 to 331.8 nm, Preliminary investigation into color centernbehavior has been performed involving crystal cooling, He-Ne pump probenexperiments and antisolarant pumping
