Title :
Parametric interactions in a dielectric medium with second-harmonic space-time pump modulation
Abstract :
Dispersion diagrams are given for the parametric coupling between the space-time harmonics of an electromagnetic wave propagating in an infinite dielectric medium whose dielectric constant is modulated by a high-intensity pump wave containing two harmonics. The effect of the amplitude and the phase of the second harmonic of the pump wave on the parametric growth process is studied. Both stable and temporally unstable interactions are considered.
