研究目的
Investigating the generation of terahertz (THz) radiation by the beating of two intense cosh-Gaussian laser beams in rippled density magnetized plasma under the relativistic–ponderomotive regime.
研究成果
The amplitude and efficiency of THz radiation generation are significantly enhanced by increasing the decentered parameter, magnetic field strength, and density ripple amplitude. The study demonstrates the potential of using cosh-Gaussian laser beams in magnetized plasma for efficient THz radiation generation.
研究不足
The study is theoretical and numerical, lacking experimental validation. The practical implementation may face challenges related to the precise control of laser beams and plasma conditions.
1：Experimental Design and Method Selection:
The study involves an analytical and numerical approach to investigate THz radiation generation by the beating of two cosh-Gaussian laser beams in magnetized plasma. Higher-order paraxial-ray approximation is used.
2：Sample Selection and Data Sources:
The study uses plasma with rippled density and applies a static magnetic field. Parameters include laser beam intensities, initial beam waist widths, plasma density, and magnetic field strength.
