Propagation of the reconstructed probe from Fig. 3, with weighted intensity contributions from each probe mode. (a) The beam intensity integrated along the x-plane, showing the vertical beam waist in the yz-plane. (b) The beam intensity integrated along the y-plane, showing the horizontal beam waist in the yx-plane. The sample position and focal plane are labelled by the white dashed line at 0.0 mm and −2.7 mm, respectively. (c) Horizontal and vertical profiles of the intensity of the beam at the focus position. (d) Horizontal and vertical profiles of the intensity of the beam at the sample position. |
