Type-I intermittency route to chaos in passively Q-switched Tm:YLF laser emitting at 2.3 μm [PDF]

EPJ Web of Conferences
We report on an original chaotic dynamic behaviour of a passively Q-switched 2.3-μm Thulium laser operating on the 3H4 → 3H5 transition. The experiment employs a Tm:LiYF4 laser crystal within various laser cavity configurations, involving optional ...

Estimation precision of degree of polarization in the presence of signal-dependent and additive Poisson noises [PDF]

Journal of the European Optical Society-Rapid Publications, 2008
We address precision of estimation of the degree of polarization (DOP) from the orthogonal state contrast image (OSCI) in the presence of both signal-dependent Poisson noise due to useful signal, and additive Poisson noise due to dark current and / or ...

Endothelial Dysfunction in Fabry Disease Is Related to Glycocalyx Degradation

Frontiers in Immunology, 2021
Fabry disease (FD) is an X-linked multisystemic lysosomal storage disease due to a deficiency of α-galactosidase A (GLA/AGAL). Progressive cellular accumulation of the AGAL substrate globotriaosylceramide (Gb3) leads to endothelial dysfunction.

Measurements and modeling of high groove density multilayer gratings for EUV spectral range in classical and conical mountings

Journal of the European Optical Society-Rapid Publications
In this work, we study high groove density gratings coated with periodic or aperiodic multilayers, focusing on their extreme ultraviolet performance in both classical and conical diffraction geometries.

Study of tapered microfibers by line-field confocal optical coherence tomography

Journal of the European Optical Society-Rapid Publications
We present for the first time to our knowledge measurements of the evolution of the core and cladding diameters in tapered silica microfibers using LC-OCT. The results could help refine models of propagation of optical modes in tapers.

Pre-existing anti-drug antibodies in Fabry disease show less affinity for pegunigalsidase alfa

Molecular Therapy: Methods & Clinical Development, 2022
We analyzed the cross-reactivity of anti-drug antibodies (ADAs) against agalsidase-alfa and -beta from 49 patients with Fabry disease (FD) against the novel PEGylated enzyme pegunigalsidase-alfa (PRX-102).

Plasmonic interferences of two-particle N00N states

New Journal of Physics, 2018
Quantum plasmonics lies at the intersection between nanophotonics and quantum optics. Genuine quantum effects can be observed with non-classical states such as Fock states and with entangled states.

Rapid and non-destructive nanofiber diameter measurement using Spontaneous Four Wave Mixing [PDF]

EPJ Web of Conferences
We will present a rapid and non-destructive technique for the measurement of the mean diameter of a silica nanofiber using the wavelength position of the signal peak in a spontaneous four wave mixing experiment.

Quantum statistics of light transmitted through an intracavity Rydberg medium

New Journal of Physics, 2014
We theoretically investigate the quantum statistical properties of light transmitted through an atomic medium with strong optical nonlinearity induced by Rydberg–Rydberg van der Waals interactions.
