Abstract

The embodiment of the invention provides a self-accelerating light generation method and device, relates to the technical field of light beams, and aims to obtain required self-accelerating light by creating a light field and increasing a linear phase. According to the specific scheme, the method comprises the steps of creating a light field of self-accelerating light; performing Fourier transformon the light field to obtain the amplitude and the initial phase of the self-accelerating light; determining a phase value, the phase value including an initial phase and a linear phase; and loadingthe amplitude and the phase value to a light path generation device to obtain the light source.

Description

technical field [0001] The present disclosure relates to the field of light beam technology, in particular, to a method and device for generating self-accelerating light. Background technique [0002] The self-accelerating beam under the self-defocusing nonlinear condition usually refers to the beam whose propagation path appears "curved", and the most representative one is the Airy beam. The spectrum-space amplitude of the Airy beam is Gaussian, and the phase is the spatial frequency. The third power; according to the amplitude and phase characteristics of the Airy beam, it is usually generated by phase modulation in experiments. [0003] It is found that the frequency spectrum and spatial amplitude of self-accelerating light under self-defocusing nonlinear conditions are not all common Gaussian or plane waves, so they cannot be obtained by phase modulation. Contents of the invention [0004] The present disclosure provides a method and device for generating self-acceler...
