Efficient master-oscillator-amplifier system utilizing copper vapor laser active elements

V. V. Zubov, N. A. Lyabin, A. D. Chursin


Abstract: An investigation was made of the temporal, spatial, and energy characteristics of a system consisting of a master oscillator, a spatial filter, and a power amplifier constructed on the basis of GL-201 and UL-102 sealed commercial laser active elements. The questions of raising the operating efficiency of such a system and obtaining high-power radiation with the diffractionlimited divergence were considered. When GL-201 active elements were used in the oscillator and amplifier, the radiation output power in a beam having a divergence close to the diffraction limit was 30-35 W. This was 3-4 times higher than the output power of the oscillator alone.
