Abstract

Pulsed dye lasers are representing a most important group of tunable lasers that can used for high resolution photographic, interferometric, holographic or spectroscopic apr cations. For our investigation we developed a multichannel nitrogen laser emitting trair of short duration light pulses (five or ten ns-pulses at repetition rates up to 100 MHz which is used either directly as UV source or as a pumping source for dyes. The waveleng can thus be converted throughout the large spectral range of dyes available and can be changed from pulse to pulse within a few ns. Some examples are given showing the applicE bility of the system for the study of rapidly expanding phase objects by means of cineme ographic techniques such as shadowgraphy or multiwavelength-interferometry.
