WebThe paraxial Helmholtz equation admits a Gaussian beam with intensity I (x, y, 0) = A_0 ^2 exp [-2 (x^2/W^2_0x + y^2/W^2_0y)] in the z = 0, with the beam waist radii W_0x and W_0y in the r and y directions, respectively. The contours of constant intensity are therefore ellipses instead of circles. Write expressions for the beam Web27 mrt. 2024 · In the present paper, we have investigated the self-focusing of zeroth-order Bessel–Gaussian beams in collisional plasma with density ripple. Based on Wentzel–Kramers–Brillouin and the paraxial ray approximations, the nonlinear differential equation governing the evolution of beam-width parameter is evaluated. The variation of …
