TL;DR: Using a recently developed method for the three-dimensional nanotomography of optical vector fields, this work fully reconstructs the light polarization structure in the focal region, confirming the appearance of Möbius polarization structures.

TL;DR: In this paper, the dispersive properties of a q=1/2 plate, specifically its group index difference Δng for ordinary and extraordinary polarization light, can be tuned for achieving single-aperture, alignment-tolerant stimulated emission depletion (STED) nanoscopy with versatile control over the color combinations as well as laser bandwidths.

TL;DR: A bird’s-eye view of the progress of this technology in recent years is presented and some educated guesses on the most likely future developments are offered.

TL;DR: This work presents an approach for direct femtosecond laser surface structuring based on optical vortex beams with different spatial distributions of the state of polarization, which are easily generated by means of a q-plate.

TL;DR: Zapf et al. as mentioned in this paper reported the origin of multiferroicity of (CH3)2NH2Mn(HCOO)3 via direct observation of ferroelectric domains using second harmonic generation techniques.
