FIELD: physics, optics.
SUBSTANCE: proposed laser comprises master oscillator, preamplifier, beam shaper system, Faraday isolator, Keppler telescope, polariser, main two-way amplifier built around rod active elements of neodymium glass and frequency doubler. Said main two-way amplifier comprises one or several pairs of identical quantrons with rod active elements of neodymium glass arranged sequentially in the beam and accumulating at least 200 J each in one pumping pulse, lens, Faraday spinner and SBS cell with radiation therein focused by said lens. Note here that polarisation 90-degrees spinners are arranged between rod active elements of quantrons inside every pair.
EFFECT: laser with pulse energy of several hundreds of Joules and repetition rate of at least 0,02 Hz for pumping of said titanium-sapphire multipetawatt complex.
