Abstract
A cw-pumped Nd:YAG oscillator followed by a cw-pumped, multipass, travelling wave amplifier using a face-pumped, total internal reflection (TIR) Nd:YAG slab as the gain element, has produced a TEM00, diffraction limited beam with up to 150 W of average power. The oscillator has been operated in the Q-switched, modelocked, and Q- switched/modelocked output formats. When the oscillator is Q-switched at a rate of 12 kHz, the system produced over 90 W of average power; with a Q-switched/modelocked oscillator at a Q-switch rate of 10 kHz the system produced over 80 W (50 W at 3 kHz). The output of this laser system has been used to generate the 532 nm second harmonic in lithium triborate (LBO), and to synchronously pump a degenerate OPO which utilized six potassium titanyl phosphate (KTP) crystals as nonlinear converters.
