    Generation of an Ultra-Long Optical Needle Induced by an Azimuthally Polarized Beam

    Generation of an Ultra-Long Optical Needle Induced by an Azimuthally Polarized Beam by Liwei Liu, Lifang Shi, Fanxing Li, Siyang Yu, Simo Wang, Jialin Du, Min Liu, Bo Qi, Wei Yan

    Published 2021-01-01

    In this manuscript, a method of generating an ultra-long optical needle (depth-to-width ratio 37.5:1) is proposed and demonstrated by focusing an azimuthally polarized beam. In theory, the action mechanism between the incident beam and the amplitude modulation element, the spiral phase modulation el...
