Abstract

Experimental and theoretical comparison of supercontinuum generation for femtosecond and nanosecond pulses with similar peak power level in the same nonlinear media was provided. In the case of femtosecond pumping, we observed a number of peaks and in the case of nanosecond pulses, we observed a continuous spectrum.
