    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.

    Gas density measurement of pulsed gas jets using XeF four-photon fluorescence induced by a KrF laser (1992)
    Springer
    Applied physics 55 (1992), S. 323-326

    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.
