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.

Evolution Period

The evolution of elliptical hollow Gaussian beams propagating in strongly nonlocal nonlinear media is investigated. As examples, this paper mainly focuses on the evolutions of the transverse intensity and the beam width of elliptical hollow Gaussian beams with the beam order being 1 and 3. The results show that the evolutions of the transverse intensity and the beam width are both periodical and the size of the evolution period is determined by the input power. There exists the transverse reverse transform for the beam width when selecting a proper input power, which is quiet different from the circularly symmetric hollow Gaussian beams.
