Abstract:
We report soft x-ray spectra (5–18 nm) from a cryogenically cooled nitrogen gas jet irradiated by 28-fs-laser pulses at an intensity of ∼7×1016 W/cm2. While the time-integrated spectrum obtained at room temperature showed exclusively transitions in N4+ ions, spectral lines from N5+ and N6+ charge states appeared with cooling. Rapid, nonlinear increase of x-ray emission on lines from N4+, N5+, and N6+ has been observed by lowering the preexpansion gas temperature.
