Abstract

K-shell x-ray at about 3 keV emitted from Ar clusters irradiated by 110mJ 55 fs intense laser pulses is studied. The x-ray flux is optimized by moving the nozzle away from the focus of the laser pulse. The total flux of K-shell x-ray photons in 4π reaches a maximum of 4.5×109 photons/shot with a conversion efficiency of 2.5×10−5 when the nozzle displacement is 2 mm and a long plasma channel is observed by a probe beam.
