Measurements of 160-fs, 248-nm ultrashort pulses are obtained through
a two-photon fluorescence measurement based on the two-photon-induced
color-center fluorescence in fused-silica crystals. The method proved
to be reliable and advantageous in comparison with two-photon fluoresc
ence techniques employing other materials, both solid state and gaseou
