| 中文摘要 | in this paper, we briefly summarize two typical morphology characteristics of the self-organized void array induced in bulk of fused silica glass by a tightly focused femtosecond laser beam, such as the key role of high numerical aperture in the void array formation and the concentric-circle-like structure indicated by the top view of the void array. by adopting a physical model which combines the nonlinear propagation of femtosecond laser pulses with the spherical aberration effect (sa) at the interface of two mediums of different refractive indices, reasonable agreements between the simulation results and the experimental results are obtained. by comparing the fluence distributions of the case with both sa and nonlinear effects included and the case with only consideration of sa, we suggest that spherical aberration, which results from the refractive index mismatch between air and fused silica glass, is the main reason for the formation of the self-organized void array.
