Abstract

A cw-lamp-pumped Nd:YAG injection-mode-locked seeded master oscillator-amplifier beamline is used to pump various optical parametric oscillators (OPOs) using KTP, KNbO₃, AgGaS₂, and AgGaSe₂ crystals as the nonlinear materials. A comparison of these materials is presented and limitations on their ultimate power scaling are identified. This program has demonstrated tunable output in the 3 - 5 mm wavelength spectrum using a mode- locked and Q-switched (MLQS) pulse waveform at low power. A novel injection-mode-locked seeded Nd:YAG laser was developed to pump the OPOs that provided MLQS pulses at > 20 W and up to 10 kHz.
