Room-temperature operation of a Fe~(2+): ZnSe laser

摘要

Pulsed lasing of the Fe~(2+):ZnSe single crystal was demonstrated at room temperature. The laser action centered at 4.4 urn with pulse energies up to 1.4 mJ and an input energy slope efficiency of 11% was obtained with a 2.94 urn Q-switched Er:YAG pump laser. Continuous tuning from 3.9 to 5.1 μm was demonstrated.
