Tunable blue light source by intracavity frequency doubling of a Cr-doped LiSrAlF6 laser

Abstract

A Cr3+:LiSrAlF6 laser in Q-switched operation at 10 kHz was intracavity frequency doubled by using a LiIO3 crystal. The 230 ns tunable blue pulses were obtained in the 395–435 nm range with up to 7 mW average power at 407 nm.
