X-ray emission from laser-irradiated gas puff targets

Abstract

This letter reports the first study of x-ray emission from plasma produced by laser irradiation of gas puff targets. The gas puff targets were created by the pulsed injection of gas into a vacuum chamber. To irradiate the gas puff target a Nd-glass laser was used, which generated 1-ns pulses of up to 15 J in energy. Spatial, spectral, and temporal measurements show that intense soft x-ray emission from the laser-irradiated gas puff target is produced.
