Investigations of iodine amplifiers with an aperture of 20...200 cm are presented. It is shown that at the aperture of 200 cm and active length of La equals 720 cm it is possible to extract Ep approximately equals 40 kJ in a monopulse from the amplifier. The results of work can be used at laser fusion facilities for the energy of Ep approximately equals 106 J.

The first experiments have been carried out on the hot plasma produced during indirect illumination of microballoons containing a gaseous DT mixture at the Iskra-5 laser installation. The integrated yield of DT neutrons reached 6 X 10(9) per pulse.

The radiation energy of 30 kJ in a pulse 0.25 ns in duration has been obtained at the output of a 12-channel iodine laser.

An experimental determination was made of the recombination constant of atomic fluorine. It was found that at 300-500°K the constant representing recombination of fluorine atoms to form the fluorine molecule was KF2 = (1–2)×10–32 cm6/sec. The efficiencies of F, Ar, He, and CO2 (relative to molecular fluorine) acting as third bodies in the recombination reaction was 40, 1.3, 0.7, and 10, respectively. The temperature dependence of the photodissociation cross section of fluorine was determined in the region of maximum absorption.
