Polariton scattering from the lowest A1-symmetry TO vibrational mode in lithium niobate presents a promising approach for generating THz radiations. Nevertheless, a notable challenge hindering this technique is the generation of frequencies exceeding 2 THz, primarily attributed to the gain spectrum of Lithium Niobate centered at 2 THz and the subst...

The presentation will focus on polariton parametric scattering in a waveguide made of Lithium Niobate to generate THz radiation. We highlight an emission of ultra-short THz pulse with a spectrum centered around 3 THz with a large bandwidth of 4 THz.

The THz pulse of a few picosecond durations have been generated and detected via optical rectification and electro-optic effect within the same ZnTe crystal. An unbalanced single-shot detection scheme was performed to characterize the signal. As a result, a multicycle signal was obtained, in which two-photon absorption and other associated nonlinea...

Modifiable THz spectral shapes are important tools that facilitate the comprehensive study of phonon dynamics in condensed matter systems. The generation of narrow bandwidth THz spectra with tunable center frequency which are suitable THz forms needed to achieve such objectives are currently less studied from the table top laser-induced plasma emit...

We study the thermodynamic properties of 10 species from 5 isomeric groups with 3 atoms by providing a comprehensive data set for the molecules of astrophysical importance. Following the initial computation of the partition function q by using the GAUSSIAN 09 suite of programs (Etim and Arunan, 2017), the thermodynamics properties such as the entro...

Oil shale is an unconventional source of fuel distributed across the world with only few active explorations due to the competitive advantage price of crude oil and natural gas. However, oil shale holds important application in the context of a decline in the crude oil reserves and a spike in the oil prices. In order to prepare for the futuristic t...

The erratic supply of power experienced over time in Nigeria and other developing countries which have been detrimental to certain health (surgical), occupational and general practices can now in this recent time be eliminated by the use of an automatic changeover switch. The automatic changeover switch that was designed, constructed and tested in...
