The three-dimensional multi-parameters controllable auto-focusing-type chiral optical light

Beams with auto-focusing property and a controllable number of wave lobes are of special significance. In this work, based on the helical phase-tuning and the Airy beam, we generate a chiral optical light, which focuses with both radial and angular self-accelerations. The light using the three-dimensional (3D) velocity to control the propagation dimension and the auto-rotating property of intensity peak for the two transverse dimensions is termed as 3D auto-focusing-type chiral optical light (ACOL), which can be controlled by multi-parameters theoretically and experimentally for possessing the characteristics of chiral, focusing, acceleration, rotation, etc. Owing to these characteristics, the ACOL has promising applications in optical micro-manipulation and super-resolution imaging.
