Abstract: The properties of Nd:glass rod lasers in the heat capacity operation,including the temperature and stress distributions,are simulated and compared with the conventional pumping and cooling scheme.It is shown that the heat capacity based lasers have the noticeable advantage over conventional lasers if very higi output energy within a short time is required.
