Thermal effects in solid-state laser materials are a critical issue for designing diode-pumped solid-state lasers. An overview over temperature and stress distribution as well as their influence on the optical behavior is given. Basic analytical treatment of the rod geometry is compared with a more accurate Finite Element calculation for the case of a transversally diode-pumped Nd:YAG rod. Significant differences in the shape of the thermal lens are observed.
