Résumé: A 2.4 µm room-temperature continuous-wave Cr2+:ZnSe laser pumped by a Thulium Fiber Laser is experimentally investigated. The laser delivers up to 720 mW of output power with absorbed power slope efficiency of 52%. The laser is tunable from 2294 to 2678 nm. Gain-switching is also demonstrated by using a Pulsed Erbium Fiber Laser pump source. A maximum pulse energy of 0.36 µJ is achieved with an absorbed threshold of 0.28 µJ and an absorbed power slope efficiency of 41%.
