Abstract
In this letter, we report a multifunctional high-performance Nd:glass laser system. Laser pulses
from an all-fiber front end are first amplified by a regenerative amplifier to 10 mJ level, and then further
amplified in a four-pass amplifier. The laser system can provide 10.3-J, 3-ns laser pulses at 1053-nm
wavelength. The shot-to-shot energy stability is better than 1.5% (RMS). The output laser beam is near
diffraction limit. Binary amplitude masks are used to maintain a flat top near-field profile with a 71% fill
factor. After the frequency conversion process, 7 and 5.5 J pulses at 526.5 and 351 nm are obtained,
respectively.
