Summary[edit]
| Description |
English: comparison of Bessel and gaussian beams
top: both have the same 1/e^2 width of the (first) maximum; bottom: integrated intensity (over the plot region) is equal for both The graphics was created using Gnuplot (source see below) and post-processing in Inkscape. |
