For the non-uniform pumping and cooling to the thin disk-type laser medium, the district cooling method for thin disk-type laser medium is proposed and examined both experimentally and theoretically. Based on heat conduction equation, the distributions of temperature and stress in end pumping thin disk-type laser medium with evenly cooling and district cooling are calculated. The results show that the tensile stresses on the edge of gain medium with evenly cooling are changed into the low values of compressive stresses for the case of district cooling, and the distribution of temperature in medium with district cooling is much more uniform than with evenly cooling, the ranges of temperature reduces about 86%, and this result is consistent well with the experimental result. The district cooling method could provide a new way of thermal management for thin disk-type laser.
