    Notes: Abstract A single picosecond ultraviolet pulse has been generated based on mode-locking of a dye laser pumped by a long pulse XeCl laser to serve as the input source for a high-power ps KrF laser system. A short-pulse uv dye laser (BBQ) pumped by an additional XeCl laser was used to selectively amplify a single pulse from a mode-locked pulse train with the pulse separation of 3.2 ns. The amplified single pulse was frequency-doubled to 248 nm with the pulse duration of 20 ps.

    Notes: Abstract A 180-fs UV pulse has been generated based on a hybrid synchronously pumped mode-locked dye laser for a multiterawatt KrF laser system. The pulse width was measured by the single shot autocorrelation technique with the three-photon fluorescence of the XeF C-A transition. The pulse width broadening due to dispersive media was investigated. The results show that the observed pulse width broadening from 210 fs to 390 fs through the entire system is explained mostly by the linear dispersion of the optical elements for near-transform-limited input pulses.

    Notes: Abstract Nonlinear processes in UV optical materials were investigated by using 280-fs, 248-nm pulses. Nonlinear absorption in CaF2 was confirmed to be a two-photon process by using the luminescence of self-trapped excitons, which was also used for the single shot pulse width measurement. The absorption bands due to F centers were identified in CaF2, MgF2, and LiF after several hundred shots at 100 GW/cm2. Absorption at 248 nm was considerable especially in MgF2 and LiF. Self-focusing and self-phase modulation were observed in CaF2.

    Notes: Abstract The gas densities of two pulsed gas jets were measured together with spatial and temporal distributions by the XeF fluorescence induced by a KrF laser. The B-X and C-A transitions of XeF showed a biquadratic dependence on laser intensity when SF6 was used as the F donor instead of F2, and quadratic and cubic dependences on gas density, respectively.
