Role of Density Profiles for the Nonlinear Propagation of Intense Laser Beam through Plasma Channel

Figure 1

Plots for density ramp 𝑅(𝜉) with the dimensionless distance of propagation 𝜉 for different types of axial inhomogeneous plasma. Here 𝐵 = 0.2. Curves I, II, and III correspond to linear, parabolic, and exponential density profiles, respectively.
