“…Although being the case of a Gaussian input beam the most studied situation in CR for cylindrically symmetric beams [33,[61][62][63][64][65][66][67][68][69], other works have investigated CR for Laguerre-Gauss beams [70,71] and for top-hat beams [72].…”

“…As we move away from the focal plane in the axial direction, the CR rings become wider and the Poggendorff splitting disappears. The on‐axis intensity grows from being zero at the focal plane to two axial intensity maxima, named Raman spots, symmetrically placed at Z=±4/3ρ0.Among all possible cylindrically symmetric input beams, Gaussian inputs have frequently been considered for CR investigations . Other works have investigated CR for Laguerre–Gaussian beams , for top‐hat beams , and for radially/azimuthally polarized input beams .…”

“…The crystals, cut along one of their optical axes, were 14 mm long and had a CR radius of R 0 0.24 mm [20]. The beam from an unpolarized He-Ne laser λ 632.8 nm was focused by a lens f 100 mm.…”

“…If the condition ρ 0 1 is satisfied,the intensity pattern at the focal plane will form by two bright rings separated by a dark (Poggendorff) ring. [18][19][20][21][22][23]. This pattern of concentric rings can, while illuminated with blue-detuned light, be used to create an repulsive ring shaped guiding potential for cold atoms and BECs [24].…”
