Temperature and wavelength dependent refractive index equations for MgO-doped congruent and stoichiometric LiNbO3
نویسنده
چکیده
We present wavelengthand temperature-dependent refractive index equations for 5% MgO-doped congruent PPLN and for 1% MgO-doped stoichiometric PPLN crystals valid for a wide spectral and temperature range. The dispersion equations were derived from quasi-phase-matched nonlinear interactions with these two crystal compositions in the near and midinfrared. The results show a good agreement with previously published frequency conversion experiments. PACS 42.65.Ky; 42.65.Yj; 42.70.Mp

Uniform MgO-doped near-stoichiometric LiNbO(3) was successfully grown from Li-rich melts by a melt supplying technique. Periodically poled domains were demonstrated in MgO-doped near-stoichiometric LiNbO(3) wafers. Efficient quasi-phase-matched difference frequency generation was achieved in a titanium-diffusion waveguide based on periodically poled MgO-doped near-stoichiometric LiNbO(3). The c...
متن کاملTemperature dependent refractive index and absorption coefficient of congruent lithium niobate crystals in the terahertz range.
Optical rectification with tilted pulse fronts in lithium niobate crystals is one of the most promising methods to generate terahertz (THz) radiation. In order to achieve higher optical-to-THz energy efficiency, it is necessary to cryogenically cool the crystal not only to decrease the linear phonon absorption for the generated THz wave but also to lengthen the effective interaction length betw...
متن کامل1 Growth and Properties of Ru Doped Lithium Niobate Crystal
Ruthenium (Ru) doped lithium niobate (LiNbO3) single crystal was grown by the Czochralski method from a congruent melt composition. The color of the Ru: LiNbO3 was red and darkened with the increasing Ru concentration. The amount of Ru concentrated in the grown crystal gradually decreased along the pulling direction because the effective segregation coefficient of Ru in lithium niobate is great...

We derive new temperature dependent Sellmeier equations for the extra-ordinary and ordinary refractive indices of 0.5% MgO-doped stoichiometric LiTaO3 crystal. The equations are based on quasi phase-matched frequency conversion measurements, as well as on interferometric measurements of the thermal expansion and thermal dispersion. These equations fit experimental data over wide spectral ranges...

ZnO and ZnO: Mn nanocrystals synthesized via reverse micelle method. The structural properties nanocrystals were investigated by XRD and Transmission electron microscopy (TEM). The XRD results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. The various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...
