Nonlinear lossy light bullets in self-focusing media with nonlinear absorption
Miguel A. Porras
We review the properties of nonlinear, multidimensional localized waves whose stationary propagation is sustained by a dynamic equilibrium between self-focusing and nonlinear losse…
Gaussian beams diffracting in time
Miguel A. Porras
We show how to transform the mathematical expression of any monochromatic paraxial light beam into the expression of a pulsed beam whose diffraction is switched from the axial dire…
Quasi-ideal dynamics of vortex solitons embedded in top-hat nonlinear Bessel beams
Miguel A. Porras
Nonlinear Bessel beams in self-defocusing media are found to be the natural, non-diffracting background where vortex solitons can be nested, interact and survive for propagation di…
Lorenz curve of a light beam: evaluating beam quality from a mayorization perspective
Miguel A. Porras, Isabel Gonzalo, M. Ahmir Malik
We introduce a novel approach for the characterization of the quality of a laser beam that is not based on particular criteria for beam width definition. The Lorenz curve of a ligh…
Stationary and stable light beam propagation in Kerr media with nonlinear absorption with controllable dissipation patterns
Miguel A. Porras, Carlos Ruiz-Jiménez, Márcio Carvalho
We report on the stationary and robust propagation of light beams with rather arbitrary and controllable intensity and dissipation transverse patterns in self-focusing Kerr media w…
Nonlinear vortex light beams supported and stabilized by dissipation
Miguel A. Porras, Carlos Ruiz-Jiménez, Márcio Carvalho
We describe nonlinear Bessel vortex beams as localized and stationary solutions with embedded vorticity to the nonlinear Schrödinger equation with a dissipative term that accounts…
