Tailoring a vortex array with equal energy distribution via nonlinear optics
How to prepare and engineer an orbital angular momentum (OAM) array is crucial for optical micromanipulation, large-alphabet optical communications, and optical image processing. Here, by leveraging nonlinear frequency conversion, we propose a scheme for tailoring an OAM array in the manner of controlling light with light. Specifically, by guiding two fundamental waves into a nonlinear optical crystal, one of which carries a Dammann vortex grating (DVG) and the other carries a Gaussian or vortex mode, we equivalently construct a nonlinear DVG in a nonlinear crystal. Thus, we can prepare a one-dimensional and a two-dimensional vortex array particularly with equal energy distribution. Our present scheme can be directly extended to engineering other spatial modes and enrich the toolkit for light field engineering. Also, this nonlinear manner could inspire more attempts in the fields of structured light nonlinear optics.
