Abstract
We demonstrate the first observation of x-ray fluorescence resulting f
rom inner-shell photoionization by a subpicosecond laser-produced plas
ma x-ray source. 8 keV electrons produced by a 100 fs laser at 3 x 10(
16) W cm(-2) intensity create K-shell vacancies in a Ti layer. This ge
nerates a 4.51 keV K alpha x-ray pulse which is used to photoionize a
Ca sample. Fluorescence of Ca at 3.69 keV (K alpha) and 4.01 keV (K be
ta) is observed as 8 result of Ti K alpha photoionization.
