Rapidly tunable and compact coherent Raman scattering light source for molecular spectroscopy1. (20th June 2014) - Saint‐Jalm, Sarah
Abstract We present a rapidly tunable (over 400 cm − 1) and compact (0.7 m 2 footprint) coherent Raman scattering light source performing both coherent anti‐Stokes Raman scattering and stimulated Raman scattering microspectroscopy. We use spectral focusing of a femtosecond Ti:Sapphire pulse and a redshifted soliton generated in a photonic crystal fiber to reach suitable spectral resolution and to rapidly acquire spectra by means of a delay line translation. The coherent Raman scattering light source is used to monitor the molecular equilibrium shift between hydrogen phosphate and dihydrogen phosphate ions under pH change.
