Abstract

Here we report for the first time mid IR OPO with LGS. The sample was only 8.2 mm long, with an aperture of 5 mm (along Z-axis) x 7 mm. It was cut at θ=90°, φ=40.6° for eo-e type-II phase-matching in the X-Y plane and AR-coated with a single layer of YF₃ centered at 1250 nm. The 10-mm long linear cavity was formed by a 10-cm radius of curvature (RC) input output coupler on a 3-mm thick YAG substrate (highly reflecting the signal and highly transmitting the pump and idler waves) and a 5-cm RC Ag total end reflector.
