On a Stability of a Q-Switched Laser Pulse Form

Abstract

The effect of an inhomogeneity of population inversion at an initial Q -switched time on the stability of the giant pulse from of a laser in an axial multimode oscillation was analysed numerically for the laser equation with an unrealistic assumption that the ratio of a cavity relaxation constant to a frequency difference between neighbouring modes is unity, principally Results indicate that for three mode oscillation there may be an initial spatial distribution of population which would uniform the giant pulse from irrespective of initial field value.
