Generation of high‐power radiation in terahertz frequency range 0.3–10 THz is a fast
developing research area attracting considerable interest over the past years due to its …

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 a calibration scheme for terahertz wave nonlinear-optical detectors based on
spontaneous parametric down-conversion. Contrary to the usual low wavelength pump in …

The influence of disordering of one-dimensional quasi-phase-matched structures in
nonlinear-optical crystals on the spectral characteristics of parametric processes is studied …

The effect of the structure of angular modes of an optical–terahertz biphoton field appearing
in strongly nondegenerate parametric down-conversion on the possibility of measuring …

Работа посвящена теоретическому исследованию влияния структуры угловых мод
оптикотерагерцового бифотонного поля, возникающего при сильно-невырожденном …

We present a method of measurement of the extraordinary refractive index dispersion in MIR
for periodically and aperiodically poled nonlinear crystals with unknown or uncertain …

Principal parameters of the nonlinear-optical crystals are analyzed, which govern the
spectral sensitivity of the terahertz wave detectors based on the frequency conversion from …

We develop a technique for detailed analysis of aperiodically poled crystalline nonlinear
transfer functions. The method allows precise evaluation of 1D aperiodic domain structure …

Terahertz (THz) wave generation in a periodically poled Mg: LiNbO_3 crystal was detected
by a pump-probe technique and analyzed using frequency and time-frequency spectra …
