(a) Light intensity distribution examples on the distal irradiated plane for the input laser diameters of 5.0, 7.2, 13.0, 31.9, and 81.9 \(\mu\)m. All images were normalized by the maximum gray value in each image (unit: mm). (b) NAGV at various distances from the center of ROI. (c) Histograms of the diameter of the circle including 50\(\%\) of the total gray value in the region of interest.
