Abstract

Nanosecond AgGaS2 type-I singly resonant optical parametric oscillator pumped by a Q-switched 1.064 µm Nd:YAG laser is demonstrated experimentally. Continuously tunable 2.6–5.3 µm radiation and output pulse energy up to 0.6 mJ at 4 µm are achieved in a single-stage conversion process. The analysis of pump threshold is investigated both theoretically and experimentally.
