The average effective mass of charge carriers produced by an intense ultrashort laser pulse in a transparent solid increases significantly as the excitation mechanism changes from multiphoton transitions to interband tunneling. We theoretically investigate this phenomenon for several dielectrics and semiconductors. For diamond as a representative dielectric, we present a detailed analysis of the laser-induced change of optical properties. When the concentration of free carriers is high, we find…

Optical Bloch modeling of femtosecond-laser-induced electron dynamics in dielectrics.

A model based on optical Bloch equations is developed to describe the interaction of femtosecond laser pulses with dielectric solids, accounting for optical-cycle-resolved electron dynamics, and also accounts for material optical properties as nonlinear polarization response.

Strong-Field Resonant Dynamics in Semiconductors.

It is predicted that a direct band gap semiconductor resonantly excited by a strong ultrashort laser pulse exhibits a novel regime: kicked anharmonic Rabi oscillations, which is strongly coupled to intraband motion.
