Self-Focusing of Hermite-Cosh-Gaussian Laser Beams in Plasma under Density Transition
Figure 1
Variation of beam-width parameter with the normalised propagation distance () with a plasma density ramp. The normalized parameters are (a) , (blue curve), (red curve), and (black curve) at decentered parameter and (b) , (blue curve), (red curve), and (black curve) at decentered parameter .
