Abstract: The thermal-lens effects of side-pumped solid-state lasers are studied and heat exchange equation is established.The temperature and thermal stress of laser medium in different pumping condition are analyzed by finite element method.Some compensation on thermal-lens effects is discussed.Thermal focal distance in different compensation condition is compared through experiment.
