Abstract

The invention discloses a generation device and a generation method for self-split light beams. The generation device sequentially comprises, along a light path direction, a light source, a space light modulator used for carrying phase modulation on a laser beam and then outputting light beams with specific light intensity distribution in a transmission manner, a rotary scatterer through which the laser beam generates incoherent lights with specific light intensity distribution, a thin lens used for acquiring partially coherent light bundles with coherent structure function forms which are incoherent light intensity Fourier transform functions, and a Gaussian filter sheet used for modulating the light intensity distribution of the partially coherent light bundles into Gaussian light intensity distribution, and generating partially coherent light bundles with specific space correlation functions, that is, the self-split light beams. According to the generation device and the generation method disclosed by the invention, the self-split light beams are generated by virtue of a light field space correlation structure regulation technology, and the self-split light beams can be simply and conveniently generated in a laboratory, thus laying a foundation for applications for the self-split light beams in the fields of atom operation and control, and the like.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a device for generating a self-split beam and a method for generating the same. Background technique [0002] Since the invention of the first laser, the coherence theory of light field has been extensively studied, among which the coherence of light beam is the most important research content of light field coherence theory. The coherence of light beam includes two aspects, namely time coherence and space coherence. The former is closely related to the monochromaticity of the beam, and the latter is closely related to the directionality of the beam. The spatial coherence of the beam endows the beam with a new degree of freedom, and provides a new idea for the regulation of the spectral density distribution, polarization structure, and coherence structure of the light field. The spatial coherence structure of partially coherent light can be characterized by the correlation funct...
