Light guides based on terbium-doped borate glass

open access: yesOptical Materials: X, 2022
Luminescent light guides on the basis of barium borate glass are studied. The light guides are optically-activated with different amounts of trivalent terbium ions.

Frequency stabilization of an ultraviolet semiconductor disk laser [PDF]

open access: yes, 2013
We report a tunable, narrow-linewidth UV laser based on intracavity second-harmonic generation in a red semiconductor disk laser. Single-frequency operation is demonstrated with a total UV output power of 26 mW. By servo-locking the fundamental frequency

Structure–property relationship and spectroscopic studies of BaO–B2O3 oxide glasses containing ZnO for optical applications

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2022
In the present work, samples of barium borate glasses containing different molar ratios of ZnO were prepared using the conventional melt-quenching technique. X-ray diffraction studies confirmed the amorphous nature of the studied materials.

The anisotropic Kerr nonlinear refractive index of the beta-barium borate (\beta-BaB2O4) nonlinear crystal [PDF]

open access: yes, 2013
We study the anisotropic nature of the Kerr nonlinear response in a beta-barium borate (\beta-BaB2O4, BBO) nonlinear crystal. The focus is on determining the relevant $\chi^{(3)}$ cubic tensor components that affect interaction of type I cascaded second ...

Observation of the quantum paradox of separation of a single photon from one of its properties [PDF]

open access: yes, 2016
We report an experimental realization of the quantum paradox of the separation of a single photon from one of its properties (the so-called "quantum Cheshire cat"). We use a modified Sagnac interferometer with displaced paths to produce appropriately pre-

Immediate versus water-storage performance of Class V flowable composite restoratives [PDF]

open access: yes, 2006
Objectives The aims of this investigation were to clarify the effects of 24 h water-storage and finishing time on mechanical properties and marginal adaptation to a Class V cavity of eight modern flowable resin-composites.
