Focal Flat Top Beam Shapers

Focal Flat Top Beam Shapers

Focal Flat Top Beam Shapers

  • Shapes Gaussian Beams to Airy Disk Profile
  • Flat-top or Doughnut Output Beam Profiles
  • Near 100% Efficiency

Focal Flat Top Beam Shapers are used to transform Gaussian beams to airy disk profiles, allowing for control of the intensity distribution of the laser spot. The output beam is shaped with nearly 100% efficiency to a flat-top or doughnut beam profile. Focusing a beam after a Flat Top Beam Shaper leads to the loss of the flat top profile. Focal Flat Top Beam Shapers provide an alternative solution by generating an Airy-disk beam profile that can be focused to obtain a flat top beam. These beam shapers feature a compact design with inner and outer threading, making them easy to integrate into equipment. Focal Flat Top Beam Shapers are advantageous for beam shaping in micromachining applications, including scribing and PCB drilling, as well as micro-welding applications. Multiple models are available at Nd:YAG wavelengths with compatible input beam diameters as small as 3mm and up to 23mm.
