Parameters of the beam obtained in run #84 with combinations of lenses CRL1 (2, 6) and CRL3 (3, 4, 6): intensity profile in the spot with the smallest size (waist at Z = 0) in the vertical direction (a) and horizontal direction (b); dependence of beam radius rz (FWHM = 2rz) on position Z in the vertical plane (c) and horizontal plane (d). Experimentally measured data (black squares) are compared with theoretical caustics (colored lines). |
