The temperature fields and stress fields of solid-state heat-capacity laser(SSHCL) and solid steady state laser were analyzed by finite-element analysis. The distance between LD arrays and laser crystal is 3.5 mm, LD array power 4 200 W×2, LD bars interval is 0.4 mm, While luminescence area 1 μm×5 mm, frequency 100 Hz, pulse width 100 μs, temperature of crystal and cooling water 20 ℃. The calculation reveals that the temperature on SSHCL surface is even higher than that in its interior, but the inverse phenomenon is found in solid steady state laser. The extremum temperature difference in solid steady state laser is 3.1 times than that in SSHCL, with there values being 19.8 ℃ and 6.4 ℃ respectively. The extremum temperature grads in solid steady state laser is 4.8 times than that in
