Paper Abstract

Experimental results of the laser pulse amplification research of the powerful iodine two-pass amplifier on 'Iskra-5' facility are presented in this report. Input and output of radiation in the two-pass amplifying scheme were realized in the far field through spatial filter. The amplifier with 8m active length and 30 by 30 cm2 aperture was used. This amplifier was pumped by electro- discharge sources of multiple operations. The 400 mm- diameter liquid saturable absorber was used as optical shutter in the two-pass scheme. It is shown that for less than 1 J energy of input laser pulse, the energy of output pulse is 1 kJ. The obtained experimental data are satisfactory agreed with results of theoretical model This mode is based on the rate equations of laser pulse propagation along active medium without regard of energy losses and relaxation of excited iodine sublevels.
