Abstract
An experiment has been performed to analyse a nonlinear lensing effect in a flashlamp pumped Cr3+:LiSAF laser which has been found to be adiverging lensing effect. The latter is due to the refrctive index change which is assumed to be proportional to the excited ion population. The corresponding constant of proportionality has been measured from the time variation of the laser pulses far-field divergence.
