Self-focusing of higher-order asymmetric elegant Hermite-cosh-Gaussian laser beams in collisionless magnetized plasma

Self-focusing of asymmetric finite Airy-Gaussian laser beams in magnetized plasma

“…By solving Eq. (10) with 𝜌𝜌 + (𝑎𝑎, 𝑒𝑒 + ) = 𝜌𝜌 − (𝑎𝑎, 𝑒𝑒 − ), an expression for the critical initial intensity parameter 𝑒𝑒 * in case of 𝐸𝐸 and 𝑂𝑂 modes of propagation can be written as…”

“…super Gaussian [3], cosh-Gaussian [4], Laguerre-Gaussian [5], Hermite-Gaussian [6], quadruple Gaussian [7], 𝑞𝑞-Gaussian [8], Bessel-Gaussian [9] and Hermite-cosh-Gaussian [10] beams due to their specific characteristics.…”

Nonlinear Propagation of Gaussian Laser Beam in Magnetized Plasma: Effect of Oblique Magnetic Field

“…In the presence of wiggler magnetic field, third harmonic generation has been reported by Sharma et al [18]. An importance of asymmetry in the beam profile has been highlighted by Vhanmore et al [19,20] in collisionless magnetized plasma. An influence of light absorption in magnetized plasma has been reported by Vhanmore et al [21] for asymmetric laser beams.…”

Self-Focusing of Gaussian Laser Beam in an Axially Magnetized Plasma

“…The nonlinear measure of dielectric function is varying according to physical circumstances but its dependence on intensity of input beam is a common feature. For collisionless magnetized plasma 𝜺 𝟎 and 𝝓 can be written as [19][20][21], Here 𝝎 𝒑 , 𝝎 𝐜 and 𝝎 are the electron plasma frequency, electron cyclotron frequency and frequency of laser used, 𝒆 and 𝒎 are the charge and rest mass of electron respectively, 𝑴 is the mass of ion, 𝒏 𝟎 is the equilibrium plasma density, 𝑲 𝑩 is the Boltzmann constant, 𝑻 𝟎 is an equilibrium plasma temperature, 𝑩 𝟎 is an external magnetic field which is assumed to be applied along (forward) as well as opposite (reverse) to the direction of propagation of laser beam, 𝝈 is the parameter associated with magnetization. For the case of forward (reverse) magnetization 𝝈 = +𝟏 (𝝈 = −𝟏).…”
