Paper Abstract

The spectrum of the supercontinuum generated by a femtosecond Ti:Sapphire laser beam in photonic crystal fiber (PCF) is increased into the UV using small core diameter PCF with zero dispersion wavelength (ZDW) shorter 600 nm. A flat spectrum is generated that spans from 350 to 1000 nm. The SC was used as an excitation source for fluorescence spectroscopy. Fluorescence spectra can be detected from dye molecules, and native molecules in tissues samples with excitation from wavelengths extracted from ultrafast SC light in the spectral range between 350 to 500 nm using narrow bandpass filters. A Streak Camera was used for time-resolved fluorescence measurements.
