Abstract: Five W-alloy specimens, containing 8.57% Ni, 6.34% Cu, and 1.34% Mo, were bombarded with 5.2 MeV singly charged nitrogen ions. The ions dose range was 5 × 1014–1 × 1016 ions/cm2. XRD patterns portrayed diffraction peaks of pure W… read more here.

Abstract: Singly ionized nitrogen molecules in ambient air pumped by 800 nm femtosecond laser give rise to superradiant emission. Here, we study this superradiance by injecting a pair of resonant seeding pulses at different intensity ratios… read more here.

Abstract: We report on a spectral splitting effect of the cavity-less lasing emission of nitrogen ions at 391.4 nm pumped by 800-nm femtosecond laser pulses. It was found that with the increase of the nitrogen gas pressure… read more here.
