We present the results of the experimental testing of the laser facility LA
MBDA, created and built at the Institute of Experimental Physics of the Rus
sian Federal Nuclear Center for generation of quasi-steady-state laser fiel
ds 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 n
s; a target chamber with an input objective focusing the RR beam to a micro
n-size spot, and a 280-mm-diameter parabolic mirror with the focal length a
lso of 270 mm; a two-stage iodine amplifier with the small signal gain coef
ficient 3 . 10(5) per one pass, to the input of which radiation from the ta
rget chamber formed by the (microobjective + parabolic mirror) system is ap
plied; a phase conjugating device with the system for the selection of the
phase-conjugated component, which allows us to realize the pulse compressio
n in the amplifier stages, and to provide the compensation of the optical a
berrations after the second pass amplification and focusing of high-power r
adiation into the microvolume; a complex for diagnostics of plasma and lase
r radiation parameters.
