Two types of polarization of the crossing wave beams: (a) s-polarization (wave electric field is perpendicular to the plane of crossing, (b) p-polarization (wave electric field is in the plane of crossing).
Profiles of the breakdown-prone for several values of the ratio of the wave power density to the breakdown threshold.
The functions characterizing the breakdown-prone volume versus the ratio of the wave power density to its breakdown threshold. The blue, red, and green lines show results of the accurate calculations (AV) and the cylindrical (CL) and prolate spheroid (PS) approximations, respectively.
Transverse profiles of the wave intensity in crossing wave beams in the focal plane for crossing angles: (a) 15°, (b) 30°, (c) 45°, and (d) 60°.
Normalized volumes of the breakdown region as functions of for several crossing angles: α = π/12 (dark blue), α = 5π/48 (green), α = π/8 (red), α = π/6 (light blue), and α = π/4 (purple).
The normalized volume as the function of the normalized power for the crossing angle π/4: the dashed lines show the volume contained in the main peak, the solid lines show the volume calculated with the account for the side peaks.
Normalized volumes of the breakdown region in the case of -polarization for different crossing angles: α = π/12 (dark blue), α = 5π/48 (green), α = 3π/24 (red), α = π/6 (light blue), and α = π/4 (purple).
Comparison of two types of volumes in the case of -polarization: solid blue—volume with varied beam width; dashed green—volume with constant beam width; (a) α = π/12, (b) α = π/6, (c) α = π/4, and (d) α = π/3.
Cross-sectional area of the breakdown-prone volume in the focal plane.
The maximum of the ratio versus normalized power density for different crossing angles; (a)— -polarization, (b)—p-polarization.

Radial profiles of the wave beam intensity in the focal plane in the absence of atmospheric turbulence (solid blue curve) and in its presence for several values of the turbulence parameter (so ).
Attenuation factor as the function of the ratio for the normalized wave number equal to (a) and (b).
Normalized breakdown-prone volume as the function of the ratio for several values of the normalized wave power and different cross angles: (a) 15° and (b) 30°.
