The gas puff target in a form of an elongated gas sheet is produced by pulsed injection of gas through a slit nozzle using a high-pressure electromagnetic valve. The method of generation of soft X-ray lasers using a laser-irradiated gas puff target has been developed at the Institute of Optoelectronics. The collaborative experiments were performed at various laser laboratories using high-intensity laser systems to irradiate the gas puff target and pump the X-ray laser active medium. Results of these experiments are presented and discussed. Works aimed at increasing the efficiency of X-ray lasers using a longitudinally irradiated gas puff target are also reviewed.}, type={Artykuły / Articles}, title={X-ray laser emission from a laser-irradiated gas puff target}, URL={http://journals.pan.pl/Content/111758/PDF-MASTER/(53-2)103.pdf}, keywords={X-ray lasers, laser-produced plasmas, X-ray optics, gas puff target}, }
