Influence of lattice modifier on the nonlinear refractive index of tellurite glass
We studied the influence of different lattice modifiers (Nb2O5, Bi2O3, or TiO2) on the nonlinear refractive index of a tellurite glass matrix by using the Z-scan technique. Based on the ability of the lattice modifiers to ...
Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...
Nonlinear refractive index measurements in antimony-sulfide glass films using a single beam nonlinear image technique
(Elsevier B.V., 2006-04-15)
The nonlinear refractive index, n(2), of films based on the new glass system Sb(2)O(3)-Sb(2)S(3) was measured at 1064 nm with laser pulses of 15 ps, using a single-beam nonlinear image technique in presence of a phase ...
Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
Ultrafast third-order optical nonlinearities of heavy metal oxide glasses containing gold nanoparticles
(Elsevier BVAmsterdam, 2014-02)
This work reports on the third-order nonlinear properties and the response time of GeO2-Bi2O3 glass, as well as the effect of gold nanoparticles on these properties. The nonlinear refractive index spectrum and the nonlinear ...
Third-order nonlinearities and other properties of molybdenum lead-pyrophosphate glass
(Elsevier B.V., 2015-04-01)
Glasses in the binary system (100-x)Pb2P2O7-xMoO(3), with x = 10-80 mol%, were synthesized by conventional melt-quenching technique. Thermal analysis, linear optical absorption, refractive index measurements, Raman scattering ...
