"Laser plasma created in nitrogen gas puff target is studied as a source of monochromatic radiation with the wavelength of 2.88 nm. The wavelength corresponds to the quantum transition 1s2-1s2p of helium like nitrogen ion. The prevailing abundance of these ions is expected if nitrogen plasma is heated up to temperature 40 ~ 80 eV. Spatial developments of plasmas and its radiation characteristics induced by various laser pulses are simulated by 2D RMHD code Z*. Namely, the results found for two different Nd:YAG laser pulses (600 mJ/7 ns) and (520 mJ/170 ps) with nitrogen gas at 1 bar pressure stimulated by experiments done in LLG are presented here. The evaluated duration of in-band radiation is 1.5 ns for 7 ns laser pulse, whereas it is 620 ps for 170 ps pulse. The energy of monochromatic radiation is ~25 times higher for 170 ps pulse. The computer results correspond properly to the laboratory experiments. Further computer simulations enable us to judge the effect of laser energy, pulse duration and wavelength on the spatial and time characteristics of this monochromatic SXR source." .
