Polarization-induced modulation of a femtosecond nonlinear process

We present experimental evidence of laser-induced polarization preference for the highly nonlinear phenomenon of supercontinuum generation. Such results have been arrived through the choice of isotropic and anisotropic materials interacting with femtosecond laser pulses of changing ellipticity. Experimental evidence of additional polarization effects is also present in anisotropic materials. Laser polarization emerges as an important control parameter that exhibits counterintuitive dependence in generating the corresponding high-order nonlinear phenomenon.
