Abstract
An original absorption probe technique using a laser plume as a probe source of UV–visible continuum radiation is proposed and tested. To our knowledge, this is the first time that laser plume emission is used as a UV–VIS (190–510 nm) probe beam in transient absorption spectroscopy. The technique allows virtually single-shot recording of continuous fluorescence and absorption spectra and proved its applicability even when used at a high-voltage high-current e-beam gun facility with a high level of electromagnetic interference. The developed technique is applied to record the transient absorption spectra of e-beam-excited Ne, Ar, and Kr gases.
