Compact high-power, pulsed, single-frequency MOPA laser system with 20 W average output power

Pulsed, single-frequency laser sources have a potential use in laser spectroscopy or LIDAR application. We present a compact and reliable MOPA laser system with a small laser line width. The system is based on a passively q-switched, monolithic single-frequency master oscillator (NPRO) and a four stage Nd:YVO4 power amplifier. The amplifier was developed… (More)
