We simulate the optical breakdown process of dielectrics under the intense laser field employing the first-principle method. Our result for the diamond, which is typical dielectrics, shows the saturation of the energy absorption and electron excitation. We found also the induced field by the surface charge becomes out of phase to the applied field.
