Book Description
We have achieved 150 mW of cw output at 4.3 micrometers, using difference frequency mixing in a singly resonant optical parametric oscillator (OPO). We pumped the OPO cavity, which contains periodically poled LiNbO3 (PPLN), with a 14-W 1.06-micrometers Nd:YAG laser to generate a signal at 1.7 micrometers and an idler at 2.8 micrometers. Mixing of the two waves at the same crystal temperature and grating spacing yielded emission in the mid IR. This technique avoids the mid-IR absorption-high-threshold problem, which has limited the cw performance of PPLN OPOs at wavelengths beyond 4 micrometers. Provided that tunability is not required, this method is a simple alternative to multiple-crystal configurations.

Book Description
Optical parametric oscillation (OPO) with intracavity sum-frequency generation (SFG) of the signal and pump has been studied theoretically and numerically, using the CW plane wave theory as well as a numerical code developed to simulate either synchronously pumped pulse propagation or walk-off effects in one transverse dimension. The configuration where the SFG crystal precedes the OPO crystal in the cavity gives stable high-efficiency conversion over a larger range of pump intensity, as well as lower power loading on the OPO crystal. About 85 percent conversion efficiency from 1.064 microns to 589 nm is predicted at pump intensities up to 9 MW/sq cm for a device using AgGaS2 and KTP crystals. Also, the angular distribution of parametric fluorescence from AgGaS2 has been calculated in good agreement with measurements made at the Phillips Laboratory.
