中文摘要	a novel double-slab nd:yag laser, which uses face-pumped slab medium cooled by liquid with different temperatures on both sides, is proposed. the thermal distortion of wavefront caused by the non-uniform temperature distribution in the laser gain media can be self-compensated. according to the method of operation, the models of the temperature distribution and stress are presented, and the analytic solutions for the model are derived. furthermore, the numerical simulations with pulse pumping energy of 10 j and repetition frequencies of 500 and 1000 hz are calculated respectively for nd:yag laser medium. the simulation results show that the temperature gradient remains the approximative linearity, and the heat stress is within the extreme range. then the absorption coefficient is also discussed. the result indicates that the doping concentration cannot be too large for the high repetition frequency laser. it has been proved that the high repetition frequency, high laser beam quality, and high average output power of the order of kilowatt of nd: yag slab laser can be achieved in this structure.
