Beam recombination device for phase-conjugated double-pass amplifier

摘要

The device recombines timewise displaced beams of several phase-conjugated double-pass amplifiers, whereby a beam of a laser oscillator pulsed with a predetermined frequency f is spatially separated in several beams of the frequency f//N, where N is the number of the amplifiers. The separated beams are amplified independently of each other in phase-conjugated double-pass amplifiers, and are recombined conditionally through the phase conjugation, automatically to a resulting beam.
