Multichannel waveguide CO2 amplifier with input from a phase-locked multichannel master oscillator

摘要

Under conditions of mutual coherence of the amplified laser beams the power and axial brightness amplification for the two-channel version of the amplifier are experimentally measured. Numerical investigations of the amplifier radiation characteristics are carried out including a random spread of the parameters of separate channels both for the two-channel and multichannel amplifier.
