Abstract
Time resolved spectrum with both high temporal resolution (∼10 psec) and spectral resolution (∼0.6 Å) of the 2ω0 harmonic emission scattered at 90° to the laser axis are presented in this paper. It is shown experimentally that the primary and secondary peaks of the 2ω0 harmonic are actually composed of many fine and bright fringes with intervals of about 1.5∼3 Å for each, the values of which are in close relation to the atomic weight. Finally, analyses and discussions of these are given.Keywords
