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.
