Nonlinear reflection of few-cycle light pulses off a bloomed dielectric interface

Fresnel formula for the normal incidence of light is generalized to the case of reflection of broad-spectrum radiation off a dielectric with nonresonant dispersion and nonlinearity. Considering reflection of few-cycle light pulses off a bloomed dielectric interface, we show that self-division of a reflected pulse: can occur at low incident intensities, while substantial modification of the pulse shape including self-compression is possible at higher intensities.
