%X We discuss the limitation of classical Drude Model, solve the kinematics equation for electrons in the few-cycle laser field, and calculate the photon absorpti on of conduction-band electrons(CBE) and impact ionization under irradiation of few-cycle ultrashort laser pulses. The effects of laser intensity, carrier-en velope-phase on impact ionization are discussed.
