High-energy laser summators based on the phenomenon of stimulated Raman scattering

The theoretical, technical and technological aspects of the high energy and low angular divergence laser beam obtaining by means of Raman's scattering application in the secondary cascade are discussed. Several (2 - 6) unphased, independent, simultaneously working primary cascades were combined into one laser beam having 10 cm diameter and 1015 - 1016 W/cm2 .sterad brightness at 40% summing efficiency.
