“…Cr:ZnSe lasers are thus very interesting as affordable, compact, room-temperature operational and broadly tunable mid-IR laser sources for use in a variety of remote sensing applications [41,42]. Cr:ZnSe can also be used for mid-IR OPO pumping such as ZGP-or CdSe-based OPOs [43,44]. In order to get Cr:ZnSe lasers even more compact, challenging research is currently oriented toward electrical pumping of a Cr:ZnSe laser.…”

“…As shown in Fig. 38, where published output powers and energies are reported as a function of emission wavelength [44,96,[100][101][102][103][104]106,107], the best performance has been obtained with ZGP-based OPSs. Indeed, up to 30 W average power have been demonstrated at high repetition rate as well as 30 mJ (signal + idler) pulse energy at low repetition rate.…”

“…More recently, the first CdSe-based device emitting more than 1 W of average power has been reported [44]. It consists in a Cr:ZnSe laser-pumped, intracavity CdSe OPO with signal and idler tunable from 3.2 to 3.8 µm and 8.2 to 8.5 µm respectively and output power of 2 W (signal + idler) at 5 kHz repetition rate.…”

Power performance of a compact, broadly tunable, continuous-wave (cw) Cr 2+ :ZnSe laser pumped by a thulium fiber laser at 1800 nm was investigated. In the lasing experiments, a Cr 2+ :ZnSe sample with a small-signal differential absorption coefficient of 11 cm-1 and a fluorescence lifetime of 4.6 µs was used. An astigmatically compensated x-cavity with 15 % output coupler produced as high as 640 mW of output power at 2480 nm with 2.5 W of incident pump power. Resonator losses were investigated using three different methods, and an in-depth analysis of the results was performed. The stimulated emission cross section values determined from laser threshold data and fluorescence measurements were in good agreement with each other. Finally, broad, continuous tuning of the laser was demonstrated between 2240 and 2900 nm by using an intracavity Brewster-cut MgF 2 prism and a single set of optics.
