Abstract

The authors describe a new approach to fluorescence excitation in supersonic jets using Fourier transform spectroscopy. This method utilizes the throughput advantage of a Michelson interferometer to achieve much higher photon fluxes. The current optical system provides a power density of 400 μW/nm in the jet - a thousandfold increase over that previously achieved with a monochromator system. Furthermore, spectral resolution down to 0.1 cm-1 is routinely achievable. The principle of Fourier transform fluorescence excitation (FTFE) spectroscopy is demonstrated for rotationally cooled iodine in a free jet expansion.
