Abstract

We have investigated the spectroscopic and laser properties of LiCaAlF6, or colquirite, doped with Cr3+ ions. The crystal seems quite promising as a laser host, as the material has been observed to crystallize well and to lase with a rather low threshold of 50 mW of pump power when utilizing 1 % output coupling. We have conducted preliminary measurements of the slope efficiency with 5% output coupling and have found the values to be comparable with those reported for alexandrite, which is currently recognized to be the most efficient Cr3+ solid-state laser.
