HIGH SPECTRAL AND TEMPORAL RESOLUTION OF PULSED EMISSIONS BY FOURIER TRANSFORM SPECTROMETRY

R. Stringat , G. Fabre , A. Ross , A. Topouzkhanian

By slaving a pulsed laser (a few kHz) to a Fourier transform spectrometer of the "continuous scanning" type [BOMEM DA3], high resolution spectra of the pulsed emission can be obtained in the IR, visible and UV regions. By inserting a fast gated integrator between the detector (PMT) and the amplifier in the sequence of data acquisition elements in the spectrometer, it is possible to record time resolved spectra for which the temporal resolution is imposed by the response time of the detector, typically 10-20 ns.
