Item Compression of femtosecond krypton fluoride excimer laser pulses(1993) Cote, Frederic; Sauerbrey, Roland A.Temporal characteristics of compressed femtosecond KrF pulses are measured with the help of a single-shot phase-sensitive autocorrelator for the UV. The performance of a prism compressor and the influence of higher order phase dispersion on the ultimate pulse width of compressed pulses is investigated. Self-phase modulation of high intensity femtosecond KrF pulses in MgF$\sb2$ is reported. The nonlinear refractive index n$\sb2$ (7.4 $\times$ 10$\sp{-16}$ $\pm$ 1.5 $\times$ 10$\sp{-16}$ cm$\sp2$/W) of MgF$\sb2$ is derived from the recorded broadened spectra. Implications of self-phase modulation in solids for compression of femtosecond KrF pulses are discussed.
