Intensity Evolution

The interaction of two four-petal Gaussian beams propagating in strongly nonlocal nonlinear media is investigated. The results show that the intensity evolution of two beams during their propagation is periodical, which is similar to that of a single beam propagation. However the combined optical field of two beams during propagation is more complicated than that of a single beam. During propagation, the two beams are attracted each other, and at the superposed region of two optical fields, the interference fringes appear. The influences of different beam orders and different input powers on the propagation properties are also discussed.

Nonlocal Nonlinear

Based on the Collins formula in strongly nonlocal nonlinear media (SNNM), the analytical expression for Lorentz beam passing through SNNM has been derived. It is found that the propagation behavior of Lorentz beam is variable and closely related to the parameters of initial ellipticity [Formula: see text] and input power. The beam has its own critical power in [Formula: see text] and [Formula: see text] directions, respectively. If the Lorentz beam with critical power in a certain direction enters in SNNM, its beam width will remain constant in that direction during propagation, otherwise its beam width varies periodically, as either broad or compressed. Moreover, when [Formula: see text], the beam spot is always symmetrical in [Formula: see text] and [Formula: see text] directions; when [Formula: see text], the beam spot is no longer symmetrical in [Formula: see text] and [Formula: see text] directions. Numerical simulations are carried out to illustrate these quintessential propagation properties.
