For the scheme of two colour lasers in interference and holography, we uncover the
remarkable contribution of the focusing region (spread) of the peak intensity of superposing …

In recent years, terahertz (THz) radiation has become an extremely useful instrument in a
variety of domains, including spectroscopy, imaging, and communication, due to its …

There are a large number of studies for terahertz (THz) radiation generation, but tunable THz
sources are still a challenge since it is difficult to tune frequency, focus and intensity of the …

Considering nonlinearities due to relativistic mass variation and ponderomotive force driven
depression in the electron density, a model is developed for the self-focusing of a super …

Particle accelerators play a crucial role in modern scientific research, facilitating progress in
diverse areas such as fundamental physics and medical treatments. In this study, an intense …

Graphite nanoparticles (NPs) in two distinct geometries, ie, cylindrical and spherical, having
two different configurations of their basal planes with respect to the electric field of the laser …

In this theoretical study, we investigate the electron plasma wave excitation (EPW) by two
