Raman spectra of lithium niobate single crystals strongly doped by zinc and magnesium, it
has been established, contain low-intense bands with frequencies 209, 230, 298, 694, and …

The possibility to manage and control spectral and spatial properties of optical-terahertz
nonclassical fields generated in strongly nondegenerate parametric down-conversion is …

Frequency-angular distributions of optical signals generated via spontaneous parametric
downconversion with the Stokes idler frequency shifts 0.2–5 THz are studied simultaneously …

We study parametric down-conversion (PDC) of optical laser radiation in the strongly
frequency non-degenerate regime which is promising for the generation of quantum …

The terahertz (THz) generation efficiency in the Cherenkov optical rectification scheme can
be improved significantly if the silicon adaptor, mounted at the lateral surface of a nonlinear …

We have examined the Raman spectra of heavily doped lithium niobate single crystals (at
close-to-threshold concentrations of doping cations): LiNbO 3: Zn (4.5 mol% ZnO), LiNbO 3 …

We study dispersion of the dielectric function real part ε′ in the terahertz-frequency range
for bulk and periodically poled congruent LiNbO 3 and Mg: LiNbO 3 crystals. The …

Sideways THz generation in Mg: LiNbO3 crystal is studied considering Si-prism-lens
couplers with different output surface curvatures. A theoretical approach is developed for …

We report here the polarization switching properties of pure and MgO-doped LiNbO 3
crystals measured directly by applying an external electric field at room temperature. From …

We propose non-phase-matched sum frequency generation (SFG) as a method for
characterizing broadband multimode light. Both the central wavelength and the bandwidth …
