| Abstract: | Considered the effects of variations of the Nd:YAG characteristic parameters such an conductivity,thermal refraction and thermal expansion coefficient with temperature,the practical formulas of thermal focus length and thermal load ration have been given by solving the heat equation.The difference of thermal load ratio between the theoretical and experimental value was explained.The theoretical analysis was agreed with the observed experimental conclusion. |
