Some features of generation of spoke-shaped neodyminum lasers

Experimental results are presented on the generation properties of spoke-shaped neodymium lasers in the periodic giant pulse regime. In lasers with polished end-faces, two types of pulses were observed, corresponding to longitudinal and circular types of oscillation. It is shown that the energetic characteristics of generation in spoke-shaped neodymium lasers improve greatly when circular types of oscillation are suppressed.
