Speckle-free beam homogenizing tolerant to incident beam size and beam quality

A laser beam with a top-hat uniform intensity distribution is desired in many applications. A top-hat beam is also called a flat-top beam or a super-Gaussian beam.

Basically we have 4 different solutions to homogenize a laser beam, i.e.

(1) flat-top beam shaping for a Gaussian beam with a specific beam size and good beam quality (Will be discontinued soon)

(2) low speckle or speckle-free beam homogenizing tolerant to incident beam size and beam quality

(3) beam homogenizing with speckles, tolerant to incident beam size and beam quality

(4) beam homogenizing for incoherent beams with microlenses

The products that you are reading were designed and fabricated based on our second method of homogenizing an incident laser beam.
