A method of generating very intense UV picosecond pulses is proposed, using excimer laser as an amplifier. A UV-preionized discharge-pumped XeCI excimer laser successfully amplified the frequency-doubled picosecond pulses generated by a passively mode-locked flashlamp-pumped Rhodamine 6G dye laser, when the wavelength was tuned to the 308-nm band. The output energy per pulse was 2.5mJ (several 100MW) for 16-μJ input. Scala-bility of this system up to GW-or TW-levels is discussed in relation with the photon-trans-port equations. It is shown that the proposed scheme is a useful technique for constructing a high-power ultrashort-pulse generator in UV and VUV region. Saturable absorbers used in UV region are briefly discussed.
