“…From Figure 3, it is seen that with increase in the values of q (i.e. q = 1, 2, 3, 4, 5) critical curves shifts downwards and the curve attains its minimum value of ρ for q = ∞ (Gaussian beam) [21].…”

“…where k 0 = ω c √ ε 0 , ω is the frequency of laser beam used, k 0 is the wave number of the laser beam and c is the speed of light in vacuum. The intensity distribution of the q-Gaussian laser beam (z = 0) is given by [21],…”

“…In the recent years, many researchers have showed a significant interest in a new class of laser beam profile known as q-Gaussian laser beam [18][19][20][21][22][23][24][25][26]. Most of the studies of laser-plasma interaction have been carried out under the assumption that the intensity distributions of laser beam have a Gaussian nature [27][28][29][30][31][32].…”

In the present paper, the nonlinear features of a high-intensity q-Gaussian laser beam propagating in collisional plasma have been investigated. The collisional plasma dynamics is basically dominated by local collisional forces rather than collective actions in it. Naturally, the nonlinearity in the dielectric function of plasma due to nonuniform heating of carriers along the wavefront of the laser beam becomes important. Here in q-Gaussian beam intensity profile q can explored right from extremely low to extremely high value such as infinity. As a consequence of it studies in propagation dynamics becomes quite interesting. By following Akhmanov parabolic equation approach under Wentzel-Kramers-Brillouin (WKB) and paraxial approximations, the differential equation is set up for the beam width parameter f and is solved numerically. The significant effect of wide range of q on critical beam radius as well as on propagation a dynamic of q-gaussian laser beam have been found interesting and is presented graphically.

In current work, the beam-width parameter (BWP) equation is reduced to two variables such as q and critical beam power (p 0) which govern the propagation dynamics and intervals of critical beam power p 0 of a q-Gaussian laser beam have been investigated. The non-linear dependence of dielectric function in collisional plasma used herein is primarily because of heterogeneous heating of carriers along the wavefront of the laser beam. The influence of intervals of p 0 is further used to explore propagation dynamics of q-Gaussian laser beam in isotropic, homogeneous and collisional plasma has been studied. The Akhmanov’s parabolic equation approach under WKB (Wentzel-Kramers-Brillouin) and paraxial approximations are used in current work. The results have been found reasonably interesting which are revealed graphically and discussed.
