Near-infrared Stokes spectra from biological samples were acquired using mode-locked Ti:sapphire excitation and a novel intensifier-coupled CCD with 200-psec time gating. The fluorescence exhibits nsec decay rates, suggesting that the primary fluorophore is not iron. Potential enhancement factors for time-gated suppression of fluorescence from Raman spectra can be calculated.
