Abstract

In our search for more efficient Cr-doped laser materials, we discovered the promising colquiriite family of Cr3+ lasers, which thus far includes LiCaAlF6:Cr3+ and LiSrAlF6:Cr3+ (Cr:LiCAF and Cr:LiSAF, respectively).1 This Cr3+ family exhibits favorable laser properties in that high slope efficiencies have been attained in both laser-pumped and flashlamp-pumped laser configurations.2-4 These materials also have adequate thermomechanical properties and low thermal lensing.5 In this paper we report laser action for LiSrGaF6:Cr3+ (Cr:LiSGAF) in the laser-pumped laser configuration by using a sample of low-passive loss material obtained by Czochralski growth technique. Cr:LiSGAF is the gallium analog to Cr:LiSAF.
