Abstract

The theory of LDend-pumped solid-state lasers is analyzed, and a method that measures the effectivestimulated emission cross-section σe of laser crystal is ascertained. We compare the threshold andslope efficiency of four Nd:YVO4crystals which have different doping levels,and calculate the σeof these crystals with upper-level life-times that have measured by us. Our results showthat the 1.9at% Nd:YVO4crystal has a σeTe of 18.3 μscm2which is largest in all the four samples.
