Abstract
Physical mechanisms those interplay in generating super continuum from femto-second pulses propagated through photonic crystal fiber (PCF) have been investigated here. We compare spectrums from two distinct PCFs with different group velocity dispersion profiles to determine the most desirable spectral features such as stronger and ripple free output spectra at wavelength regions of interest, specifically around near infrared wavelength which we can use for coherent anti-Stokes Raman Scattering microscopy of lipid-rich structures. Coherency of the pulses from these two PCFs was also compared. The spectrums from theoretical model will provide us guidance for future experiments.
