LCP vortex half-waveplateRadially polarized beamMOPAHigh efficiency and High purityIn this paper, we demonstrate the generation of a radially polarized beam (RPB) with a maximum average output power of 20 W by our self-developed nanosecond pulsed ytterbium (Yb)-doped fiber MOPA system. The ...
These true zero-order, m = 2 vortex half-wave plates are designed to affect the radial and azimuthal polarization of optical fields. They have a constant retardance across the clear aperture, but a fast axis that rotates continuously over the optic (see the Graphs tab). Viewed through crossed...
As the SLM only modulates horizontally polarized light, the circularly polarized light of the vortex laser array generated from q-plate arrays is converted into horizontally polarized light using a combination of quarter- and half-waveplates (not shown in Fig. 2a). A pinhole is used to block ...
9b). The polarization-resolved mode images were captured after placing a half-wave plate and polarizing beamsplitter (for linearly polarized images) or a quarter-wave plate, half-wave plate and polarizing beamsplitter (for circularly polarized images) in front of the infrared camera (Fig. 4f–h...
We present a simple method to measure the topological charge and index of VVOFs by using a space-variant half-wave plate (SV-HWP). The geometric phase grating of the SV-HWP diffracts a VVOF into ±1 orders with orthogonally left- and right-handed circular polarizations. By inserting a ...
Geometric phase shifts, also known as Pancharatnam–Berry (PB) phase shifts, are, for example, those imparted on circularly polarized light as it passes through a half-wave plate. Here, the chirality of the polarization is inverted, and the phase of the subsequent light is determined by the...

The initial polarization state is selected by using a polarizing beam splitter (PBS), a half-wave plate (HWP) and a quarter-wave plate (QWP). Then the beam passes through an electrically tunable q-plate, whose optical retardation is controlled by applying an adjustable electric field. When ...
