Analysis on the temperature distribution and thermal effects in corner-pumped slab lasers

The temperature distribution and thermal effects in a high-power solid-state laser are investigated. The temperature distribution in a corner-pumped Yb:YAG/YAG composite slab is described analytically, and the thermal effects in that slab are deduced. Their influences to the resonator are also discussed. A corner-pumped Yb:YAG/YAG composite slab laser has achieved 1016 W continuous wave laser output. The experimental results support the calculated outcomes.
