In order to calculate the thermal effects on solid-state laser crystals such as the thermal stress, stress birefringence and thermal lensing, the temperature distribution is necessary and important. In this paper, we introduce an analytical model for

In this paper, an analytical model for temperature distribution of the side-pumped laser rod is extracted. This model can be used for side-pumped laser rods whose absorbed pump profile is a Gaussian profile. Then, it is validated by numerical results
