Paper Abstract

The generation of high power, ultrashort pulses in the UV wavelength region has important implications for nonlinear optics, photochemistry, plasma X-ray sources and dye laser pumping. Excimer lasers have sufficient bandwidth for the amplification of pulses having a duration in the picosecond range and a significant effort has been devoted to the development of short pulse sources based on these devices. The application of conventional mode-locking techniques has been investigated by several groups but has not been particularly successful in exploiting the wide spectral bandwidths available in the laser media. This has been due in large part to the limited number of cavity round-trips permitted by the relatively short duration of the gain provided by discharge-excited lasers. Thus rare gas halide lasers have been used to amplify picosecond pulses to power levels of tens of gigawatts but have depended on fairly sophisticated external sources to generate the initial ultrashort pulse. Recent experiments on stimulated Brillouin scattering from liquids have demonstrated that subnanosecond pulses can be generated from a narrow linewidth XeC1* source, and the use of this pulse shortening process may permit the development of less complex ultrashort pulse excimer systems in the future.
