Thermal distortion analysis for conduction cooled end-pumped slab
摘要
Abstract
The thermal distortion in the conduction cooled end-pumped zig-zag slab under different cooling conditions were analyzed by numerical simulation.The results indicate that the thermal distortion could be reduced by 3 orders of magnitude in zig-zag propagation.The inversion phenomenon of wave front was observed when different zig-zag optical paths were selected.The zig-zag optical path can eliminate the influence of the non-uniform heat dissipating capacity in length and height directions,but not in width direction.When the heat dissipating capacity in slab's width direction is non-uniform,the thermal distortion increases significantly and the propagation direction will be deviated.Therefore,when the heat dissipating capacity of the slab is non-uniform,small bounce number of zig-zag propagation is preferable to reduce the thermal distortion.关键词
