Operational results with fast automatic beam-based LHC collimator alignment [PDF]

, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.

Two-Dimensional Quasi-Periodic Diffraction Properties of the Scalar and Vector Optical Fields

Photonics, 2023
As is known, quasi-periodicity attracts great attention in many scientific regions. For instance, the discovery of the quasicrystal was rewarded the Nobel Prize in 2011, leading to a series of its applications.

Acoustic tractor beam [PDF]

, 2014
Negative radiation forces act opposite to the direction of propagation, or net momentum, of a beam but have previously been challenging to definitively demonstrate.

Probing the modal characteristics of novel beam shapes [PDF]

, 2013
In this thesis, an investigation into the modal characteristics of novel beam shapes is presented. Sculpting the phase profile of a Gaussian beam can result in the generation of a beam with unique properties.

Vector Beam Bending

, 2021
It is well known that the trajectory of a light beam can curve if the medium in which the beam propagates is inhomogeneous or if the local spacetime is curved.

Optical trapping with superfocused high-M2 laser diode beam [PDF]

, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.

Generating vector beams by modulating and superimposing multiple polarization modes within a helium-neon resonant cavity

AIP Advances, 2023
In recent years, vector beams, which have greater control freedom due to their non-uniform spatial polarization distribution, have received extensive attention from scholars.

Flexible Method for Generating Arbitrary Vector Beams Based on Modified Off-Axis Interference-Type Hologram Encoding

Photonics, 2022
A novel experimental setup for the generation of arbitrary vector beams is proposed. The system major includes two reflective liquid crystal spatial light modulators (RLC-SLM) and a polarizing beam splitting prism. Moreover, this method is not limited by
