Abstract

The invention discloses a non-paraxial self-accelerated frequency-doubled light beam control device and method, which is applied to the technical field of optics. The device comprises an electric field unit, a quasi-phase matching unit and a filtering unit, wherein the electric field unit is electrically connected with the quasi-phase matching unit and used for loading an electric field to the quasi-phase matching unit for generating a linear electro-optical effect in the quasi-phase matching unit; the quasi-phase matching unit is further arranged at the front end of the filtering unit and used for converting a fundamental frequency light beam from a light source into a non-paraxial self-accelerated frequency-doubled light beam according to a quasi-phase matching condition, adjusting the quasi-phase matching condition by utilizing the linear electro-optical effect to control a polarization state and the intensity of the non-paraxial self-accelerated frequency-doubled light beam, and transmitting the controlled non-paraxial self-accelerated frequency-doubled light beam to the filtering unit; and the filtering unit is used for filtering the fundamental frequency light beam passing through the quasi-phase matching unit from the received light beam to obtain the controlled non-paraxial self-accelerated frequency-doubled light beam. The device can improve the flexibility of light beam control.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a non-paraxial self-accelerating frequency doubling beam control device and method. Background technique [0002] With the rapid development of science and technology in recent years, self-accelerating beams have been applied in the field of optical micro-manipulation due to their characteristics of no diffraction and self-acceleration. Among them, non-paraxial self-accelerating beams play an important role in broadening the application of self-accelerating beams and miniaturization of optical devices because they can break through the paraxial limitation of traditional self-accelerating beams. The current non-paraxial self-accelerating beam usually changes the polarization state and intensity by changing the propagation medium, but this is a passive control method, which has the problem of insufficient flexibility. Contents of the invention [0003] The main purpose of the e...
