Abstract

We review the properties of nonlinear, multidimensional localized waves whose\nstationary propagation is sustained by a dynamic equilibrium between\nself-focusing and nonlinear losses. Their finite-energy versions preserve light\nbullet behavior well-beyond the characteristic diffraction or dispersion\ndistances, and rebuild after obstacles. There exists a preferential lossy light\nbullet with maximum intensity and losses, defined solely by the optical\nproperties of the medium, which is the most stable, non-conical localized wave\nsupported by a medium with self-focusing nonlinearity and nonlinear losses.\nThis preferential lossy light bullet acts as an attractor during self-focusing\nof Gaussian-like wave packets when collapse is halted by nonlinear absorption,\na fact that can explain relevant characteristics of the observed light filament\ndynamics in media with anomalous dispersion.\n
