ABSTRACT: This paper reviews fundamental material properties and the current state-of-the-art of continuous-wave and pulsed Cr<sup>2+</sup> doped chalcogenide lasers. Multi-watt output powers are demonstrated in both CW and pulsed modes of operation. Laser output and optical-to-optical conversion efficiency for a Cr:ZnSe laser operating at 7 kHz pulse repetition frequency are presented.

ABSTRACT: Summary form only given. We report a approach which accesses the mid and long-wave IR regions using a single ZnGeP<sub>2</sub> optical parametric oscillator (OPO) stage driven by a tunable Cr<sup>2+</sup>:ZnSe pump laser. This is the first report of a longwave Cr<sup>2+</sup>:ZnSe pumped OPO.

ABSTRACT: We describe active mode locking of a Cr(2+):ZnSe laser operating near 2.5 mum. The laser produces 4.4-ps transform-limited Gaussian-shaped pulses and produces 82 mW of average power.

ABSTRACT: We report room-temperature operation of an all-solid-state broadly tunable continuous-wave Cr(2+):ZnSe laser. Output power of 250 mW, an absorbed power slope efficiency of 63%, and continuous tunability from 2138 to 2760 nm are demonstrated.
