Self-Focusing of Hermite-Cosh-Gaussian Laser Beams in Plasma under Density Transition
Figure 2
Variation of beam-width parameter with the normalised propagation distance () with a plasma density ramp. The normalized parameters are (a) and decentered parameters are (red curve) and (black curve) at and (b) and decentered parameters are (red curve) and (black curve) at .
