Laser Plasma Monochromatic Soft X-ray Source Using Nitrogen Gas Puff Target
Original language description
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 differentNd: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
