Temperature distribution was analysed in material of a fiber coupled laser-diode end-pumped ceramic Nd:YAG laser. The critical temperature difference, which caused to fracture material, between the surface and the center of the material was analysed into 355 ℃ by calculations, and experimental results. The most important parameter to fracture material in laser was proved to be the temperature difference between the surface and the center of the material.
