Assuming the pump light to be Gaussian beam and considering the nonlinear absorption of the medium, we establish the heat conduction model to describe the thermal effects in a double end-pumped Cs vapor laser. Combined with the experimental parameters, the radial temperature distribution and accordingly the optical path difference under different pump powers are obtained by numerically solving the model. Furthermore, the influence of operating parameters on the thermal focal length is investigated.
