Abstract

Based on the avalanche model, the evolution of femtosecond laser induced micro-explosion in fused silica was investigated. The microscopic processes, including the production of conduction band electron (CBE), laser energy deposition, CBE and energy diffusion were solved by a finite element method in two-dimensional cylindrical coordinates. The accumulated net charge and the electrostatic field were also calculated. The results indicate that the CBE and energy diffusions play an important role in the micro-explosion in dielectrics.
