Efficient THz generation through laser and plasma parameter optimization with Sinh-Gaussian beams in magnetized plasma

This study presents a novel method to improve the efficiency of THz generation by optimising laser and plasma parameters and using Sinh-Gaussian beams in a magnetised plasma environment. Intense laser pulses, when combined with a pre-ionized plasma, produce powerful electromagnetic fields that can efficiently emit THz radiation. We conduct a thorough analytical study of the effects of important factors, such as plasma density, decentered parameter of Sinh function, transverse distance, and external magnetic field strength, on the efficiency of THz generation using theoretical studies. THz efficiency has positive corelation with plasma density and decentered parameter while external magnetic field has no significant effect on generated THz efficiency. The results of our study show substantial improvements in the power and spectrum properties of THz output by implementing the suggested optimisation methods. This research provides useful insights that can be used to improve THz generating techniques. These techniques have a wide range of applications, including spectroscopy, imaging, communications, and sensing.
