FIELD: lighting.
SUBSTANCE: system for amplification of light flux comprises first reflector, first aperture, first polariser, configured to reflect light radiation, characterised by first polarisation state, set of mirrors and second polariser. System also includes first and second sets of amplifier modules. Each amplifier module of first and second sets of amplifier modules includes inlet opening, quarter-wave plate, plate-amplifiers and an output window.
EFFECT: technical result consists in improvement of efficiency of suppression of spurious modes by using multipass amplification configuration.
