Abstract

Excimer laser amplifiers were used in obtaining higher-peak power ultrashort pulses in the ultraviolet (UV) wavelength region. Gain-narrowing was the major restraint on pulse shortening. A single pass stretcher-compressor with gratings was adopted in the UV region obtaining nearly transform-limited pulses of 72 fs. A broader spectrum was required for further shortening of the pulses. Ultrashort pulses of 10 fs were generated in the near-infrared region using a hollow fiber in a gas cell. This hollow fiber can also be applied to the UV light. Hence, this technique is most suitable for the generation of high-energy ultra-short pulses in the UV region.
