Abstract Adipose tissue (AT) optical properties for physiological temperatures and in vivo conditions are still insufficiently studied. The AT is composed mainly of packed cells close to spherical shape. It is a possible reason that AT demonstrates a

The dynamics of the topological charge of a vortex optical beam propagating in turbulent air while accounting for the cubic nonlinearity is theoretically considered. In a number of examples, we show that the optical beam, self-focusing, manifests its

The inverse variational problem is solved for the nonlocal nonlinear Schrodinger equation modeling filamentation processes in various nonlinear media. The corresponding integral relations generalizing conservation laws to the nonconservative case are

Properties of the integral of motion and evolution of the effective light beam radius are analyzed for the stationary model of the nonlinear Schrodinger equation describing the filamentation. It is demonstrated that within the limits of such model, f

A quasi-steady-state approximation for the problem of stimulated Mandelstam–Brillouin scattering (SMBS) in the air as in a multimode acoustic medium is formulated. In this approximation, a numerical solution of the equation for the envelope of the

A model of single filamentation of a high-power ultrashort light pulse has been developed on the basis of evolutionary dependencies of phase and amplitude parameters of the light field found from the numerical solution of a nonlinear Schrodinger equa

We present a computational modeling approach for imitation of the time-domain optical coherence tomography (OCT) images of biotissues. The developed modeling technique is based on the implementation of the Leontovich–Fock equation into the wave Mon
