摘要：

A singly-resonant OPO (SRO) based on AgGaSe2 (AGSe) intracavity pumped at similar to 1.85 mu m by the signal pulses of a Rb:PPKTP doubly-resonant OPO (DRO) provided extremely broad tuning (5.8 to similar to 18 mu m) for the non-resonated idler. In a similar set-up with the same nonlinear crystals, we studied intracavity difference-frequency generation (DFG). Both AGSe and the new monoclinic crystal BaGa4Se7 (BGSe) generated single pulse energies of similar to 0.7 mJ near 7 mu m at an overall conversion efficiency from the 1.064 mu m pump of 1.2%. The main advantage of BGSe is its damage resistivity up to the maximum pump levels applied at 100 Hz.
