Cylindrical vector cv beams
Web摘要：. Cylindrical-vector beams are of increasing recent interest for their role in novel laser resonators and their applications to electron acceleration and scanning microscopy. In this paper, we calculate cylindrical-vector fields, near the focal region of an aplanatic lens, and briefly discuss some applications. Webgreatly enhanced by employing the cylindrical polarization. Cylindrically polarized beams, generally called cylindrical vector beams, have received considerable attention in recent decades because of their unique focusing characteristics [18-23]. Radially and azimuthally polarized beams are two typical cylindrical vector beams.
