Parametric analysis of THz wave generation efficiency and plasma density using Sinh-Gaussian beams

This research conducts a thorough parametric analysis to examine the complex correlation between plasma density and the effectiveness of generating terahertz (THz) waves. Gaining a comprehensive understanding of the impact of plasma density on the efficiency of THz generation is essential for the progress of THz technology. We investigate the impact of different factors on THz generation, such as plasma density, decentered parameter, and transverse distance, using numerical simulations using Sinh-Gaussian laser beams. The results of our study demonstrate that with increase in plasma density, THz generation efficiency increases with increase in plasma density and becomes almost constant for relatively high- plasma density for the selected frequency range. THz generation efficiency increases with increase in transverse distance, becomes maximum at a specific transverse distance, then decreases continuously. This study enhances the basic comprehension of THz wave generation and offers significant insights for optimising THz sources in diverse applications using Sinh-Gaussian beams.
