Abstract
Under stable-cavity-condition,expression of thermal focal length is educed in the view of cavity.Thermal focal length of Nd:YVO4 crystal is measured,and the result is obtained in experiment.We calculate it in its traditional formula too.At last the two results is compared,and we make a conclusion that they are coincident basically.
