英文摘要: In this project, we will study the nonlinear optical properties of Airy beams and other non-planar beams. The study will cover the fundamental physical properties of Airy beams and related nonlinear optical effects, such as the nonlinear harmonic generations of two-dimensional and three-dimensional Airy beams, the second-harmonic generation, third-harmonic generation and other nonlienar optical processes of Airy beams in optical superlattices. We will also develop fast numerical calculation algorithms for efficienct numerical simulation of these nonlinear preocesses, and develop a superlattice designing method suitable for Airy beams. We will perform experiments to verify the theroical results, and extend our research from Airy beams to generalized non-planar beams such as Bessel beams and high-order Bessel beams, and study the propagating properties and phase-matching properties of bessel beams. In the end, we will develop an generalized phase-matching theory for the nonlinear processes involving non-planar beams in optical superlattices.
