Abstract

Room-temperature continuous-wave laser action in a novel Tm-doped Li Lu F 4 crystal emitting at around 1.9 μ m is demonstrated. The crystal growth process, spectroscopic measurements, and laser performance are presented for different Tm concentrations. An overall tunability extending from 1817 to 2056 nm , a slope efficiency of 46%, and a maximum output power in excess of 1.1 W are reported.
