Ultrafast Sources for Nonlinear Spectroscopy


Abstract: We have developed an extensive suite of tools to broaden the application range of near-IR ultrafast laser sources, including all normal dispersion supercontinuum generation, a master oscillator power amplifier, and a high speed pump-probe delay scanner. Our primary goal for the development of these methods and techniques was to enable a series of coherent Raman experiments, where we have the capability to explore the sensitivity of different excitation schemes: impulsive excitation, vibration specific excitation, and spontaneous Raman scattering, in addition to a similarly varied set of detection methods. We will also seek to employ these techniques of nonlinear fiber interactions to other ultrafast laser platforms. Specifically, we will suitably alter the power spectrum of an Er-doped ultrafast fiber laser to perform new vibrational overtone experiments.
