Electronically tuned diode-laser-pumped Cr:LiSrAlF_6 laser

Abstract

With a liquid-crystal-based birefringent tuner in a coupled resonator, an AlGaInP diode-laser-pumped Cr:LiSrAlF(6) cube laser has been electronically tuned from 858 nm to beyond 920 nm. At an incident pump power of 42 mW, an output power in excess of 4.3 mW was observed near the peak of the tuning curve at 870 nm.
