“…[21] The oscillatory self-focusing takes place for different values of intensity parameter and with increase in intensity parameter, the distance between two consecutive points of intersection of two beams increases. [22] The laser beam is compressed and amplified in an enhanced manner by the combined effect of magnetic field, relativistic nonlinearity, and negative initial chirp. [23] It is to be noted that strong self-focusing is obtained by optimizing wavelength and intensity parameters of cosh-Gaussian laser beams.…”

Density transition based self-focusing of cosh-Gaussian laser beam in plasma with linear absorption has been studied. The field distribution in the plasma is expressed in terms of beam width parameter, decentered parameter, and linear absorption coefficient. The differential equation for the beam width parameter is solved by following Wentzel–Kramers–Brillouin (WKB) and paraxial approximation through parabolic wave equation approach. The behaviour of beam width parameter with dimensionless distance of propagation is studied at optimum values of plasma density, decentered parameter and with different absorption levels in the medium. The results reveal that these parameters can affect the self-focusing significantly.
