| 中文摘要 | we report on the damage threshold in caf2 crystals induced by femtosecond laser at wavelengths of 800 nm and 400 nm, respectively. the dependences of ablation depths and ablation volumes on laser fluences are also presented. we investigate theoretically the coupling constants between phonon and conduction band electrons (cbe), and calculate the rates of cbe absorbing laser energy. a theoretical model including cbe production, laser energy deposition, and cbe diffusion is applied to study the damage mechanisms. our results indicate that energy diffusion greatly influences damage threshold and ablation depth. |
