Flat-top beam
WebTwo approaches for generating flat-top beams (uniform intensity profile) with extended depth of focus are presented. One involves two diffractive optical elements (DOEs) and the other only a single DOE. The results indicate that the depth of focus of such beams strongly depends on the phase distribution at the output of the DOEs. By having uniform phase … WebThe schematic of beam shaping is shown in Fig. 1. An example of the shaped beam is given in Fig. 2 while its measured flat-top intensity distribution is shown in Fig 3. Fig 1. Beam Shaping Schematic. Fig 2. Flat-Top Beam. Technical reminder: Only circular flattop pattern can be created and input beam must be Gaussian and collimated.
