Two-color Time-resolved Spectroscopy of Helium Using High-order Harmonics

Larsson, Jörgen LU orcid ; Mevel, E ; Zerne, R ; L'Huillier, Anne LU orcid ; Wahlström, Claes-Göran LU and Svanberg, Sune LU (1995) In Journal of Physics B: Atomic, Molecular and Optical Physics 28(3).
Abstract
The radiative lifetime of the 1s2p(1)P state of helium is measured in a two-colour ionization experiment with a 5% accuracy. The state is excited by the 13th harmonic of a tunable 80 ps laser and ionized by a synchronous ultraviolet laser, with a variable time delay. This experiment demonstrates that the high harmonics generated in a jet of rare gas exposed to an intense laser field provide a tunable short-pulse xuv source ideally suited for pump/probe type of studies and, in particular, short lifetime measurements.
