Single Headlamp with Low- and High-Beam Light
Photonics, 2021 Generally, automobiles are typically equipped with separate headlamp lanterns for generating low- and high-beam light. Compared with separate headlamp lanterns, a single headlamp producing both low- and high-beam light can be more compact and have less ...

Extraction of Inherent Polarization Modes from an m‐Order Vector Vortex Beam
Advanced Photonics Research, 2022 Superposition of two independent orthogonally polarized beams is a conventional principle of creating a new light beam. Herein, it is intended to achieve the inverse process, namely, extracting inherent polarization modes from a single light beam ...

Mutually guided light and particle beam propagation
Scientific Reports, 2022 The polarizability of atoms and molecules gives rise to optical forces that trap particles and a refractive index that guides light beams, potentially leading to a self-guided laser and particle beam propagation.

A cold cesium beam source based on a two-dimensional magneto-optical trap
AIP Advances, 2022 A beam source is proposed for the production of an intense cold cesium atomic beam that can be used in cesium beam atomic clocks. The source is based on a two-dimensional magneto-optical trap (2D-MOT), but introduces hollow cooling and pushing lights in ...
