Vs. Belyaev et al., EFFICIENT GENERATION OF HIGH-POWER PICOSE COND PULSES IN A SOLID-STATE YAGND SYSTEM WITH A REGENERATIVE AMPLIFIER, Kvantovaa elektronika, 21(8), 1994, pp. 735-737
A regenerative amplifier, capable of amplifying pulses from a cw YAG l
aser, was designed and built. The pulses were of 100 ps duration and t
hey were amplified to an energy of 19 mJ. The maximum energy of a puls
e after passage through an additional single-pass amplifier, 10 mm in
diameter, reached 120 mJ. The power density of this radiation was 10(1
4) W cm-2 when focused to form a spot 300 mum in size. The energy of a
pulse converted to the second harmonic was 36 mJ.
