ABSTRACT:
Laser equipment in which pumping every dependence of output beam diameter and beam wavefront curvature is reduced. The total pumping energy of at least one of laser active media disposed beyond terminal laser beam waists, among beam waists, is approximately one-half of the total pumping energy of laser active media disposed between two adjacent beam waists.
