Gas puff laser plasma is studied as a source of water window radiation with 2.88 nm wavelength, corresponding to quantum transition ls2 - ls2p of helium -like nitrogen ions. Spatial development of plasma induced by Nd:YAG laser beam is simulated by 2D Radiation-Magneto-Hydro-Dynamic code Z*. The results for nitrogen gas layer (0.72 mm thickness, 1 bar pressure) and two different laser pulses (600 mJ/7 ns and 525 mJ/170 ps), corresponding to the experiments done in Laser Laboratory Gottingen are presented.
