CdSe optical parametric oscillator operating at 12.07 µm with 170 mW output

Research output: Contribution to journalArticlepeer-review

Abstract

A CdSe optical parametric oscillator (OPO) was demonstrated to operate at 12.07 µm with a maximum output power of 170 mW at a pulse repetition frequency of 1.2 kHz pumped at 2.09 µm with 14.64 W from an acousto-optic Q-switched Ho:YAG laser. To the best of our knowledge, 12.07 µm is the longest wavelength obtained with a 2-μm laser-pumped CdSe OPO. Besides, the angular tuning curve for type II CdSe was also investigated, and the idler wavelength from the OPO could be tuned from 10.24 to 12.07 µm.
