Abstract

We used a cw-pumped, Q-switched, and mode-locked Nd:YAG oscillator and a cw-pumped, multipass traveling-wave amplifier with a face-pumped total-internal-reflection Nd:YAG slab as the gain element to produce an 80-W, TEM₀₀ diffraction-limited beam at a Q-switching rate of 10 kHz (50 W at 3 kHz). The output of this device was used to synchronously pump a degenerate optical parametric oscillator that utilized six KTiOPO₄ crystals as nonlinear converters. A maximum average power of 14 W at 2.128 μm was generated with a conversion efficiency of 25% at 4.25 kHz.
