Generation of a terahertz supercontinuum by the self-scattering of a femtosecond pulse in the optical-rectification regime

The possibility of generating a terahertz spectral supercontinuum in the regime of the optical rectification of a femtosecond optical pulse is predicted. The transient and asymptotic stages of generation are distinguished. The supercontinuum consists of the soliton and nonsoliton components of a terahertz signal at the asymptotic stage. It is shown that the formation of supercontinuums is accompanied by a redshift of the median of the opticalpulse spectrum.
