Paper Abstract

Laser diode pumped zigzag slab Nd:YAG MOPA (Master Oscillator Power Amplifier) system featuring high pulse energy and high average power has been developed for the pumping of ultra- short pulse laser system. The MOPA system consists of an oscillator, a preamplifier, two postamplifiers and image relay telescopes. The post amplifiers has an angle multiplexed ring type double-pass configuration. A pulse energy of 1.26 J and an average power of 251 W are obtained at the repetition rate of 200 Hz. The frequency doubled power using a LBO (LiB3O5) crystal is 105 W at the repetition rate of 170 Hz. The intensity profiles of the fundamental and the second harmonic are near top hat and is suitable for the pumping. In a preliminary experiment, effectiveness of the MOPA as a pump source of all solid state chirped pulse amplifier (CPA) system is demonstrated.
