Nf. Andreev et al., A two-channel repetitively pulsed Nd : YAG laser operating at 25 hz with diffraction-limited beam quality, IEEE J Q EL, 35(1), 1999, pp. 110-114
A two-channel, repetitively pulsed laser was studied. The main features of
this laser were the compensation of aberration and polarization distortions
in Nd:YAG crystals and the summation of two channels of radiation into a s
ingle diffraction-limited beam with a pulse energy up to 5 J.
