{{M?+]p,^ Abstract: In this paper a theoretical analysis of thermal lensing in side-pumped solid-state laser is made and the distributions of pumping source and temperature gradient are discussed. A numerical solution of thermal lensing is given. Thermal lensing is measured in experiment, which is consistent with the results from the numerical solution. It is a practical way to design the DPL cavity with the numerical solution.
