A Nd: YLF regenerative amplifier with laser diode array (LDA) pumping was developed. Regenerative amplifier operating wavelength 1 0 5 3nm, repetition rate 1Hz, output 4ns wide basic mode TEM0 0 laser pulse energy of 2mJ. The total magnification reaches 1 × 107, and the output energy stability is better than ± 47% (peak value). The experimental device of regeneration amplifier and the related experimental results are given
