PROCESS OF GENERATION OF PULSE OF POWERFUL LASER RADIATION Russian patent published in 1994 - IPC

FIELD: quantum electronics. SUBSTANCE: process of generation of pulse of powerful laser radiation is based on formation of master pulse in nanosecond range of length and on its amplification in powerful two-port amplifier with non-uniformly widened amplification line and conjugation of wave radiation front. Formation of master pulse is conducted by generation of two or more single-frequency monopulses of lesser duration which frequencies satisfy relation υ_n=υ_n-1-Δν, where n = 1 st, 2nd, 3d ... number of monopulse; Δν is half-width of frequency valley in amplification circuit of two-port amplifier. Then they are summed up so that odd and even numbers of pulses correspond to orthogonal polarization and pulses of similar evenness are not overlapped in time. In this case spatial separation of each two series monopulses is carried out after first passing through amplifier before conjugation of wave front. EFFECT: improved efficiency of process. 3 dwg
