Abstract

Presented is a quantitative comparison between the thermal lens under lasing and non-lasing conditions in a laser-diode-pumped Nd,Lu:YAl3(BO3)4 laser using the lateral-shearing interferometric technique. The thermal lens under lasing conditions was reduced to 60% of that under non-lasing conditions. Above threshold, the slope of thermal lens power to pump power under lasing conditions was reduced to 50% of that under non-lasing conditions. These experimental results will find application in the design of passive Q-switched lasers using Nd,Lu:YAl3(BO3)4 crystal.
