Generation of an Ultra-Long Optical Needle Induced by an Azimuthally Polarized Beam
I whakaputaina 2021-01-01Whiwhi kuputuhi katoaIn 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...
