Figure 4
(a) Variation of beamwidth parameter with dimensionless distance of propagation for linearly (solid line) and circularly (dot line) polarized beams. Curves I, II, III, IV, V, VI, and VII correspond to = 0.5, 5, 10, 20, 60, 100, and 200, respectively. Here , , and (for linearly polarized laser beam) and 113.21 (for circularly polarized laser beam). (b) Variation of beamwidth parameter () with dimensionless distance of propagation for linearly (solid line) and circularly (dot line) polarized beams. Curves I, II, III, and IV correspond to = 10, 60, 100, and 200, respectively. Here , , and (for linearly polarized laser beam) and 64.89 (for circularly polarized laser beam).
