Abstract: Continuous-wave lasing is obtained for the first time in a Cr²⁺:CdS crystal pumped by a thulium fibre laser at 1908 nm. The output power of the laser at 2534 nm achieved 0.81 W with the slope efficiency with respect to the absorbed pump power equal to 52.3%. The parameters of Cr²⁺:CdS and Cr²⁺:CdSe lasers are compared. A Cr²⁺:CdSe crystal generated 1.7 W of cw radiation at 2638 nm with the slope efficiency with respect to the absorbed power equal to 53.4%.
