Study on the amplifier module of the ''Delfin'' installation for thermonuclear plasma heating

Principles of establishment and the optical diagram of a powerfuel laser amplifier module of the ''Delfin'' installation designed for spherical heating of thermonuclear targets are considered. Results of investigations into parameters of irradiation of the amplifier module in different regimes of operation are given. The focusing system of laser radiation on the surface of tarqets is described; results of experiments on plasma heating by the radiation of three constituent laser beams at the laser energy level up to 1 kJ at the current density up to 1014 W/cm2 are analysed
