Non-critical OPO based on periodically-poled KTP crystal generating ∼ 250 ps idler pulses at 1 - 10 kHz

Abstract

Idler pulses at 2.8 µm with energy of ∼ 50 µJ and ∼ 250 ps pulse duration are obtained from a short-cavity, singly-resonant OPO based on PPKTP, pumped by a 1−10 kHz, 500 ps, 1064 nm laser source
