Abstract
Abstract
Broadband three-stage frequency conversion of multiline CO laser radiation in a single sample of ZnGeP2 crystal was numerically studied at various crystal temperatures. Decrease of the ZnGeP2 crystal temperature resulted in enhancement of efficiency for each frequency conversion stage due to phase-matching shifting. The third stage efficiency at liquid-nitrogen crystal temperature was 1.7-fold higher as compared to one at the room temperature. Also, the crystal temperature decrease resulted in spectral broadening of frequency converted radiation.
