Аннотация
We demonstrate a laser-diode-pumped Nd:YAG slab amplifier with dimensions of 7×35×138.2 mm. The fluorescence is homogeneously distributed in the Nd:YAG amplifier, and a stored energy of 3.2 J can be achieved at 1,500 W pump power. For a repetition frequency of 200 Hz, 25 μJ injection polarized seed light, and 1,500 W pump power, the small signal gain reaches 12.66. At the same repetition frequency, 0.4 mJ with 27 ns bandwidth of injected seed-light energy and a 6×26 mm aperture, the output energy reaches 1.071 J. The extraction efficiency is 33.46% after four-pass amplification. An energy amplification from millijoules to joules is realized for the injected laser beam.
