    Lobanov, Valery E.; Borovkova, Olga V.; Kartashov, Yaroslav; Vysloukh, Victor A.; Torner Sabata, Lluís (2012-02-02)
    Article
    Accés restringit per política de l'editorial
    We reveal that the competition among diffraction, cubic nonlinearity, two-photon absorption, and gain localized in both space and time results in arrest of collapse, suppression of azimuthal modulation instabilities for ...
  • Vortex twins and anti-twins supported by multiring gain landscapes
