Abstract :
A novel laser-diode pumped eight-pass Nd:YAG zig–zag slab amplifier architecture was developed with the aim of achieving high energy-extraction efficiency. High energy-extraction efficiency of up to 71% for the laser mode volume has been achieved in this amplifier operating at an initial small signal gain of 3.25. The compensation of thermal birefringence in this amplifier was successfully performed.
