Pulse Compression of Excimer Radiation by Backward-Stimulated Brillouin Scattering in Gaseous Media

Not Accessible

Your library or personal account may give you access

Abstract

Because of the limited storage time of excimer lasers, their effective utilization for laser fusion and other short-pulse applications will require the use of pulse stacking1 or compression2 or a combination of these techniques. Raman compression of KrF lasers has been studied extensively,2,3 but the possibility of backward-stimulated Brillouin scattering in gases at excimer wavelengths has only recently been discussed.4 Gases are of interest for these applications because of the high threshold for self-focusing and breakdown and because of the potentially lower absorption losses than for liquids. As compared with backward-stimulated Raman scattering, Brillouin scattering offers less losses to higher-order processes, negligible wavelength shift, and a true phase-conjugate reflection.
