چکیده
We have shown that the optical sign of uniaxial langasite crystal Ca 3 TaAl Si 2 O 14 is positive. also measured phase-matching conditions second-harmonic generation and sum-frequency up to 3.5 µm. Simultaneous fitting these experimental data allowed us report Sellmeier equations ordinary extraordinary principal refractive indices, magnitude nonlinear coefficient.

Single crystals of nonlinear optical material bis (guanidinium) hydrogen phosphate monohydrate (G2HP) belonging to non centrosymmetric space group P 21c were successfully grown by the slow evaporation method. Optical transmittance and second harmonic generation of the grown crystals have been studied by UV-vis-NIR spectrum and Kurtz powder technique respectively. The transmittance of G2HP cryst...

In this paper, the effect of pressure, temperature and impurity on the energylevels, binding energy, linear and nonlinear optical properties of a modified Gaussianquantum dot are studied. In this regard, the finite element method is employed to solvethe single electron Schrodinger equation in the effective mass approximation with andwithout impurity at the center of the dot. In addition, the en...
متن کاملMagneto-Optical properties of GaP single crystal
The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...
