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.
