Abstract :
Summary form only given. We demonstrated for the first time the autocorrelation measurement in the extreme ultraviolet region by using the two-photon ionization of rare gases and observed 27-fs pulses at the 9th Ti:sapphire laser harmonic. The experimental setup for the autocorrelation measurement is shown. The fundamental pulses were spatially divided into two beams in a delay line before a pulse compressor.
