Abstract
In order to improve the homogeneity of pumping power in the slab,based on the designing scheme of LD dual-end-pumped Nd:YAG ceramic slab laser,the absorbed pump power density distribution of constant concentration dopant slab and gradient concentration dopant slab were theoretically analyzed respectively.After analysis,it is found that the pump absorption intensity distribution becomes non-uniform for constant concentration dopant slab when the pump absorption efficiency is improved.However,for gradient concentration dopant slab,high pumping efficiency and uniform pump absorption intensity distribution can be separately achieved,which can improve the homogeneity of pumping power absorbed in the slab.
