Abstract

Intense, subpicosecond KrF laser pulses were focused into a boron nitride plasma containing boron atom clusters. Strong soft-x-ray spectra observed suggest the production of the fully stripped boron ions with the focused laser intensity of 8 X 10¹⁶ W/cm². Time history of the Lyman-(alpha) emission (4.8 nm) indicates the production of a cold plasma with H-like B ions within tens of ps after the irradiation of the subpicosecond KrF laser pulse.
