Article
In this study, structural and thermal features of phosphate glasses doped with diluted magnetic semiconductors are investigated. The samples were ZnTe nanocrystals doped with different concentrations of Cr and Mn. UV-visible absorption spectra showed the presence of Cr²⁺ and Cr³⁺ ions into the matrix. Depolymerization of the phosphate network is ob...

In the present work, thermal and nonlinear properties of tellurite glasses doped with Tm2O3 were investigated by means of thermal lens, thermal relaxation and z-scan measurements. The composition of the samples was (78 − x) TeO2 + 4.5 Bi2O3 + 5.5 ZnO + 10.5 Li2O + 1.5 Nb2O5 + xTm2O3 (x = 0.05, 0.1, 0.5, 1.0 and 1.5 mol%). Thermal diffusivity (D), s...

A B S T R A C T K E Y W O R D S LIDAR is a well-known remote sensing instrument that is particularly has been used to measurement of atmospheric parameters. The setup basically includes a receiver and transmitter. In a bistatic LIDAR, transmitter and receiver are divided by a certain distance. The measurement of the resolution in different atmosphe...
Article
In this study, structural and thermal properties of dispersed carbon nanomaterials such as single-wall carbon nanotubes and graphene in water are investigated. Carbon nanostructures are dispersed in the fluid through surfactant and ultrasonication treatment. Structural studies of the samples are carried out by Raman spectroscopy which show that the...
Conference Paper
Here, we report CA Z-Scan results for 80TeO 2 .20ZnO: x Dy ³⁺ glasses ( x =1 . 0,2 . 0mol%). Both samples presented a self-focusing lens like behavior, with a nonlinear refractive index varying from (5 . 87 ± 0 . 04)10 ⁻ ¹⁵ cm ² /W to (20 . 37 ± 0 . 09)10 ⁻ ¹⁵ cm ² /W.

Question
We want to use 100 fs, tunable laser (680nm - 1064nm) for this setup (power: 3 W in 800 nm).
But I don't know which parameters are very important to choose the proper detector in this kind of setup.
Thanks.

Project
Our project is spectroscopy of semiconductor by different ways such as Coherent Anti-stokes Raman Spectroscopy (CARS), Z-scan, Four wave mixing in two modes of degenerate and non-degenerate. Beside of semiconductor we want to investigate nonlinear properties of other materials such as glasses.
