Intense Terahertz (THz)-wave generation and highly sensitive THz-wave detection were obtained by wavelength conversion with nonlinear optical susceptibility χ(2) of LiNbO3 crystals. Maximum peak output of about 50 kW (5 μJ/pulse) was demonstrated i

We have experimentally determined the terahertz- (THz-) wave parametric gain of stimulated Raman scattering (SRS) by phonon-polaritons in $\mathrm{LiNb}{\mathrm{O}}_{3}$. Our approach is based on ultrabright THz-wave generation from SRS under stimula

We studied the solidification and melting of certain complex scattering substances by laser Raman spectroscopy. We used a modified laser Raman system to study the spectrum of certain long-chain organic substances (paraffin and candlewax) during solid

In this article, we discuss broadband-tunable terahertz-wave parametric generation (TPG) via stimulated polariton scattering and techniques for narrowing the output spectrum of sources based on this phenomenon. The TPG effect, which is observed when

We report on the use of injection seeding to narrow the terahertz-wave linewidths of terahertz parametric light sources [a terahertz parametric generator (TPG) and a terahertz parametric oscillator (TPO)] using a LiNbO3 crystal and a Nd:YAG laser (wa

A coherent terahertz (THz) wave can be generated by difference frequency generation (DFG) using nonlinear optical crystals. DFG has a potential advantage of wide tunability achieved by a proper selection of the DFG crystal and input wavelengths. In t

The hottest frequency region in terms of research currently lies in the 'frequency gap' region between microwaves and infrared: terahertz waves. Although new methods for generating terahertz radiation have been developed, most sources cannot generate
