Theoretical and experimental studies are made of the dependences of the reflectivity of the semiconductor on physical properties of the materials and laser generated electron-hole plasma in pulse laser microprocessing. 对脉冲激光微细加工中半导体的反射率与材料物理特性及激光产生的电子&空穴等离子体的关系进行了理论与实验研究。
At higher pump densities the excitons dissociate, and the UV stimulated emission is dominated by an electron-hole plasma recombination process. 在高密度激发条件下,由于激子趋于离化,紫外受激发射主要由电子-空穴等离子体的辐射复合引起。
