Method and system for generating optical lattice by modulating Airy beam through digital mask

The invention relates to the technical field of optics, and discloses a method and a system for generating an optical lattice by modulating an Airy beam through a digital mask, a spatial light modulator is used for loading and generating pure phase distribution of the digital mask to modulate the Airy beam to obtain modulated light, and the modulated light is filtered and focused to generate the optical lattice of a target geometric structure; optical lattices with different geometric structures are obtained by changing the digital mask function # imgabs0 #, the initial optical field distribution # imgabs1 # of the Airy beam modulated by the digital mask is represented as # imgabs2 # in a cylindrical coordinate system, and the digital mask function # imgabs3 # is a spatial distribution function of discrete numbers; according to the invention, the artificially controllable optical lattice can be generated by only one laser beam, the dynamic regulation and control of the special optical lattice with a complex s
