Abstract
A theory is given of the resonant interaction between an ultrashort coherent light pulse and a semiconductor, which occurs when the pulse duration is less than the polarization or "phase memory" relaxation time. It is shown that, under certain conditions, a stationary 2π pulse can form. Numerical estimates of the velocity of propagation of a stable pulse are obtained for a typical semiconductor.
