Flat-top beam shaping for a Gaussian beam with a specific beam size and good 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 methods 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

(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 first method of homogenizing an incident laser beam.

Product nomination for diffractive top-hat beam-shaping elements

Our standard top-hat beam shaping elements include Gaussian beam to rectangular flat-top beam and Gaussian beam to circular flat-top beam.
