Abstract

Abstract

For a pulsed kJ-level high energy Nd: glass solid-state laser, temperature distributions have been numerically studied under two thermal management methods, a traditional method with a fixed cooling water temperature, and a novel method with a prompt water temperature rise after each pump pulse. The results have shown that the temperature gradient in the laser rod can be limited to a low level to ensure the high energy output laser with a high beam quality, by employing the novel thermal management method. And the optimized values of the heated water temperature rise, near the average temperature rise value caused by one pump pulse, have been calculated for different pulse intervals and different input energies. For an interval time of 15 s, the heated water temperature rise after one pump
