Laser-diode-pumped eight-pass Nd:YAG slab amplifier

A novel laser architecture of laser-diode pumped eight pass 1064-nm Nd:YAG zig-zag slab laser amplifier was developed aiming to achieve high energy extraction efficiency and good beam quality. A high energy extraction efficiency of up to 73% for the laser mode volume has been achieved in this amplifier operating at an initial small signal gain of 3.36. The excellent beam quality factor M2 of 1.2 has been obtained. The compensation of thermal birefringence in this amplifier was successfully performed.
