Measurement of 160-fs, 248-nm pulses by two-photon fluorescence in fused-silica crystals

摘要

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 fluorescence techniques employing other materials, both solid state and gaseous. (C) 1997 Optical Society of America.
