Nonlinear optical susceptibility of multicomponent tellurite thin film glasses
Tellurite TeO2–TiO2–Nb2O5 thin film glasses have been produced by pulsed laser deposition. The dispersion of the real and imaginary parts of the linear refractive index has been measured in the range from 300 to 1700 nm. Films present high refractive index n=2.01 and reduced absorption k 10−4 at =1500 nm. The nonlinear third order optical susceptibility 3 has been determined at four different w...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولOptical and Thermal Properties of Mixed Alkali Phosphate Based Glasses
Glassy samples with a composition of 40P2O5–30V2O5–(30-x)Li2O– xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...
متن کاملSpectroscopic Investigation of The Optical Properties of Rare Earth Doped Phosphate and Tellurite Glasses
Improving the up-conversion efficiency is the key issue in rare earth doped glasses. The quantum efficiency, optical gap, radiative transition rate and lifetimes of excited states are greatly influenced by the optical properties of the host material, ligand field, multi-phonon relaxation processes, impurities, temperature and concentration of rare earth ions. This presentation gives a panoramic...
متن کاملSimulation of Acoustic Properties of Borate and Tellurite Glasses
Makishima and Mackenzie model was used to simulation of acoustic properties (longitudinal and shear ultrasonic wave velocities, elastic moduli theoretically for many tellurite and borate glasses. The model was proposed mainly depending on the values of the experimentally measured density, which are obtained before. In this search work, we are trying to obtain the values of densities of amorphou...
