Abstract
A free-electron laser (FEL) microscope has been constructed to perform spatially and spectrally resolved pump/probe experiments in single living cells. Picosecond infrared FEL pulses are absorbed by the sample and rapidly converted to heat. Excitation of localized fluorescent reporter molecules using a UV/VIS probe beam leads to thermally induced alterations in the radiative signal. Fluorescence-detected infrared (FDIR) spectra are generated from regions proximal to reporter molecules by varying the FEL pump wavelength. Sub- wavelength spatial resolution is a composite function of media thermal properties and probe selectivity.
