Effects of Mirror Aberrations on Laguerre-Gaussian Beams in Interferometric Gravitational-Wave Detectors [PDF]
, 2011 A fundamental limit to the sensitivity of optical interferometers is imposed by Brownian thermal fluctuations of the mirrors' surfaces. This thermal noise can be reduced by using larger beams which "average out" the random fluctuations of the surfaces ...

Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Interferometry versus projective measurement of anyons [PDF]
, 2015 The distinct methods for measuring topological charge in a non-abelian anyonic system have been discussed in the literature: projective measurement of a single point-like quasiparticle and interferometric measurement of the total topological charge of a ...

Overview of Advanced LIGO Adaptive Optics
, 2016 This is an overview of the adaptive optics used in Advanced LIGO (aLIGO), known as the thermal compensation system (TCS). The thermal compensation system was designed to minimize thermally-induced spatial distortions in the interferometer optical modes ...

One-shot x-ray detection based on the instantaneous change in the refractive index of GaAs
AIP Advances, 2020 An interferometric semiconductor x-ray detection system is proposed in this paper. The system is based on the RadOptic effect, and it utilizes Fabry–Perot interferometry to measure radiation-induced changes in the optical refractive index of a ...

Electron interferometry in quantum Hall regime: Aharonov-Bohm effect of interacting electrons
, 2009 An apparent h/fe Aharonov-Bohm flux period, where f is an integer, has been reported in coherent quantum Hall devices. Such sub-period is not expected for non-interacting electrons and thus is thought to result from interelectron Coulomb interaction ...

Fabry–Perot interferometer as a solar background noise suppressor: application to daytime lidar
Annals of Geophysics, 2012 Continuous atmospheric probing by a lidar is a requirement for many applications. However, due to high solar background noise during the daytime, lidar operations are mostly restricted to night-time.
