In this work, we dedicated to the presentation of our results concerning the evolution of the electron density in the conduction band and the optical damage threshold (OBT). A study of the influence of the initial electronic density on the electron density in the conduction band and on the threshold of optical damage will also be presented. The main objective of this work is the theoretical study of optical damage of dielectric Materials like: Silicate by using a technique based on ultra-short and high-density laser pulses. The mains theoretical models about the OBT technique given in the literature are also studied. A new theoretical model with several improvements is proposed. This model takes into account the recombination’s mechanism with three holes. New numerical software has been developed in order to solve the PDE systems of our theoretical model using MATLAB simulation. The contribution of different mechanisms with OBT has been studied numerically. The obtained results showed that recombination mechanism with three holes plays an important role to estimate the density of free electrons and the OBT. We showed in our model that the recombination mechanisms reduce the electron density in the band of conduction is therefore increasing the threshold of optical damage (OBT). The predictions of the code developed in this study have been successfully compared to different experimental measurements of thresholds of breakdown in silica. The found results have a good agreement with experimental results.
