Paper Abstract

Coherent band spectrum renormalization in dielectrics by a strong anisotropic electric field of intense laser pulses is considered in terms of dynamic Franz-Keldysh effect (DFKE). Comparing to permanent DFKE shifts of center-zone (Γ-point) non-degenerate band extrema, DFKE band spectrum renormalization of degenerate center-zone and zone-edge band extrema occurs as their simultaneous shifts and splitting. Theory-group analysis is invoked to construct the DFKE Hamiltonian for typical dispersion curves of valence and conduction bands in dielectric materials.
