SPECTRAL AND TEMPORAL BEHAVIOR OF SLIDING-DISCHARGE EXCITED UV-IR LASER

A sliding discharge excited SF6/propane-butane/N-2 laser emitting simu ltaneously in the UV (337.1 nm; 357.7 nm) and in IR (2.6-3.2 mu m) spe ctral ranges was investigated experimentally. Laser energies as high a s 1.2 mJ in UV and 12 mJ in IR were measured. The waveforms of the vol tage, current and laser (12 ns FWHM UV and 35 ns FWHM IR) purses were obtained. The IR laser spectrum consisting of more than 20 separate li nes was registered and analysed. A spectral and temporal IR-lines inte nsity redistribution depending on the N-2 pressure was observed and ex amined.
