Abstract:We describe various generation schemes that employ soliton dynamics in photonic-crystal fibers to generate a red-shifted femtosecond pulse with high efficiency. We then detail how to use this pulse along with the initial femtosecond laser pulse for coherent Raman experiments. We describe various measurement schemes that, though utilizing this pair of femtosecond pulses, mimick the preferred measurement scheme for coherent Raman microspectroscopy where one pulse is transform-limited and of picosecond duration; or for coherent Raman microscopy where both pulses are transform-limited and of picosecond duration. We finally discuss how to increase pulse energy and give some perspective on the realization of a coherent Raman endoscope based on soliton dynamics.
