DOI: 10.1007/s11468-019-01017-5
Abstract: Through this theoretical study, nanoparticles-based Terahertz (THz) emission is explored out by considering the graphite nanoparticles (NPs) of two different shapes, i.e., spherical (SNPs) and cylindrical (CNPs), oriented in two normal directions, i.e., one having… read more here.

DOI: 10.1364/oe.533354
Abstract: Millijoule-scale pulses of multicycle terahertz radiation (MC-THz) are increasingly being pursued as drivers for applications requiring high-fields and high spectral brightness. An attractive approach for generating high peak-power MC-THz pulses is nonlinear optical down-conversion of… read more here.
