Abstract

Conversion of Q-switched 1.064µm Nd:YAG laser pulses to the 22.2µm region with 46% efficiency is demonstrated with a KTP-based type 2 phase-matched optical parametric oscillator (OPO) with two pairs of walk-off compensating crystals in a ring resonator. With 10 mJ of pump energy, we obtain 2.5 mJ at the 2.06µm signal and 2.1 mJ at the 2.2µm idler, with a beam quality of M21.4. With a ZnGeP2-based OPO pumped by the signal from the KTP OPO we achieved 14% conversion efficiency from 1.064 µm to the 35µm range.
