Paper Abstract

A multichannel atmospheric pressure N2-laser is describ-ed delivering five pulses at repetition rates of several tens of MHz and pulse durations below 1 ns. The UV-pulses at 3371 A have first been applied to study laser induced plasmas. In a second experiment they are used to pump suitably chosen dyes. It is shown that such pulses at different wavelengths are well suited for interferometric measurements up to frequencies of SO MHz. Thereby the individual interferograms are separated optically without the use of rotating mirror cameras or image converters.
