Abstract

Ultrashort (<10ps at lkeV) high-brightness (10²² photons/sec-mm²-eV into 2π steradians at lkeV) x-ray pulses are generated by exciting a preformed laser-produced plasma using a 1GW picosecond laser pulse. Time-integrated spectra and time-integrated spatially resolved emission yields are presented for various materials. Time-resolved measurements of the XUV and x-ray emission from a solid Au target are presented, as well as the dependence of radiation yield on the laser energy, angle of incidence and polarization. The production and short time duration of the x-ray emission is attributed to resonance absorption followed by rapid plasma cooling via thermal conduction.
