摘要
In this paper, we investigate the electron Bernstein wave aided beat wave of Hermite-coshGaussian laser beam absorption in a collisional nanocluster plasma. The interactions of electric field profile of Hermite-cosh-Gaussian laser beams with electron clouds of nanoclusters cause the beat wave. The nonlinear ponderomotive force is generated through the beat wave of two Hermite-cosh-Gaussian laser beams. The time average power absorption per electron per unit area per unit time by electron Bernstein wave aided electric field of laser beat wave is derived. The graphical discussions were promised to achieve extreme absorption via spatial shape of Hermitecosh-Gaussian laser beam and resonance condition of beat wave to surface plasmon frequency. The electron Bernstein waves parameters such as thermal velocity, cyclotron frequency and perpendicular component of wavenumber is also leading with beat wave for control and enhancement of absorption process in plasma embedded with nanocluster. The absorption is controlled by tuning the laser beam width, mode index, collisional frequency, clustered radius, and density.
