Experimental observation of anisotropic diffraction induced by orbital angular momentum
Guo Liang, Huicong Zhang, Lei Fang +3
We reveal for the first time a direct relationship between the diffraction of optical beams and their carrying orbital angular momentum (OAM). We experimentally demonstrate a novel…
Anisotropic diffraction induced by orbital angular momentum during propagations of optical beams
Guo Liang, Yuqing Wang, Qi Guo +1
It is demonstrated that the orbital angular momentum (OAM) carried by the elliptic beam without the phase-singularity can induce the anisotropic diffraction (AD). The quantitative…
Transition between self-focusing and self-defocusing in nonlocally nonlinear media
Guo Liang, Weiyi Hong, Yahong Hu +7
We reveal the relevance between the nonlocality and the focusing/defocusing states in nonlocally nonlinear media, and predict a novel phenomenon that the self-focusing/self-defocus…
Spiraling elliptic breathers in saturable nonlinear media with linear anisotropy
Guo Liang, Qi Guo, Qian Shou +1
We have introduced a class of spiraling elliptic breathers in saturable nonlinear media with linear anisotropy. Two kinds of evolution behaviors of the breathers, rotating and pend…
Application of canonical Hamiltonian formulation to nonlinear light-envelope propagations
Guo Liang, Qi Guo
We first point out it is conditional to apply the variational approach to the nonlocal nonlinear Schrödinger equation (NNLSE), that is, the response function must be an even functi…
Canonical equations of Hamilton for the nonlinear Schrödinger equation
Guo Liang, Qi Guo, Zhanmei Ren
We define two different systems of mathematical physics: the second-order differential system (SODS) and the first-order differential system (FODS). The Newton's second law of moti…
