Abstract

Nonlinear autocorrelation methods are widely used for measuring pulse duration of ultra-short pulses. In the ultraviolet (UV) region, since no crystal is available for second- harmonic generation, multi-photon-induced fluorescence techniques have been generally applied.1-3 But an extremely higher intensity is required for a single shot measurement. The irradiation to the nonlinear medium by the high intensity and short wavelength radiation causes pulse broadening caused by the self-phase modulation in addition to fatal degradation of the nonlinear medium.
