Diffraction-limited, high average power phase-locking of four 30J beams from discrete Nd:glass zig-zag amplifiers

摘要

A single ND:YLF oscillator beam is amplified in four discrete zig-zag amplifiers. The resulting four 30J beams are phase-locked locked using SBS phase conjugation, resulting in near diffraction-limited 120J pulses from a single aperture at up to a 1 OHz pulse repetition frequency.
