Abstract
In the present manuscript, we propose a theoretical model which defines propagation of Hermite-cosh-Gaussian laser pulse in thermal quantum plasma with density ramp. Further, differential equation for the beam width parameter is set up by taking expression for dielectric function and following WKB approximation. Comparison is done for the self-focusing with density ramp profile and without density ramp is reported. The former is more prominent in achieving stronger self-focusing of laser pulse as compared to the later one.
