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…
