TL;DR: In this article, a series of ternary glass systems namely, Na2O, B2O3, and RO (R ¼ Ba or Mg) doped with TiO2 are synthesized.

TL;DR: In this paper, the optical data are explained in terms of the different oxidation states adopted by the chromium ions into the glass network and the absorption peak at ground state exciton energy, the absorption at band gap, and the free exciton binding energy are determined.

TL;DR: A review of the optical properties of oxide glasses containing chromium or titanium is presented in this article, where the authors show that low light scattering loss is expected in these oxide glasses because they have lower glass transition temperature.

TL;DR: In this article, the glass is doped with ZnO to tune the glass absorption characteristics in a wide spectrum range (200-2500 nm). Chemical bond approach, including chemical structure, electronegativity, bond ionicity, nearest-neighbor coordination, and other chemical bonding aspect, is used to analyze and to explain the obtained glass properties such as: transmittance, absorption, electronic structure parameters (bandgap, Fermi level, and Urbach exciton-phonon coupling), Wannier free excitons excitation (applying

TL;DR: In this paper, the nonlinear susceptibility of the investigated molecule induced by pump and Stokes laser beams employed in the CARS technique is discussed, and the relation between the non-linear susceptibility, the different CARS laser intensities and the phase matching condition between them is also presented.
