Abstract

Widely tunable optical parametric oscillators (OPOs) are attractive sources for applications in mid-IR due to;the scarcity of direct-emitting conventional lasers in this spectral region. Recently, two new chalcogenide;compounds BaGa₄Se₇ (BGSe) and BaGaGe₂Se₆ (BGGSe) having relatively high χ(2) nonlinear optical coefficient;were successfully synthesized and large single crystals were grown using the Bridgman-Stockbarger technique;[1, 2]. Recently the first BGSe nanosecond OPO pumped by a Q-switched Nd:YAG laser (1.064 μm) [3] and;pumped at 2.09 μm by a Q-switched Ho:YAG laser [4] were demonstrated. Lastly, an intracavity pumped cascaded;OPO based on BGGSe was reported [5].
