We present the results of the experimental testing of the
laser facility LAMBDA, created and built at the Institute
of Experimental Physics of the Russian Federal Nuclear
Center for generation of quasi-steady-state laser fields
in microvolumes.
The facility includes: a single mode generator of reference
radiation (RR) producing about 10 mJ energy in a pulse
of controlled length from 3 to 30 ns; a target chamber
with an input objective focusing the RR beam to a micron-size
spot, and a 280-mm-diameter parabolic mirror with the focal
length also of 270 mm; a two-stage iodine amplifier with
the small signal gain coefficient 3·105
per one pass, to the input of which radiation from the
target chamber formed by the (microobjective + parabolic
mirror) system is applied; a phase conjugating device with
the system for the selection of the phase-conjugated component,
which allows us to realize the pulse compression in the
amplifier stages, and to provide the compensation of the
optical aberrations after the second pass amplification
and focusing of high-power radiation into the microvolume;
a complex for diagnostics of plasma and laser radiation
parameters.
