We present a first-principle calculation for optical dielectric breakdown induced by an intense laser field. We employ the time-dependent density-functional theory, solving the time-dependent Kohn-Sham equation in real time and real space. The calculation shows a qualitative change of electron dynamics as the laser intensity increase, above 710 $^{14}$ W/cm. Following the pulse, the excited electron exhibit a coherent plasma oscillation.
