Circularly Serrated Aperture for Beam Apodization

There is a growing demand for laser beams with uniform energy distribution (flat-top beams) in various industry sectors. It is known that beams with steep edge profiles are more prone to develop diffraction ripples. These ripples may intensify in certain optical systems e.g., amplifiers through self-focusing. In this use case, we seek to tackle this challenge by introducing a serrated beam apodizer. Beam apodization plays a key role in the design of high-energy lasers and beam delivery systems. Using amplitude-only apertures in high-energy optical systems leads to higher durability compared to apertures fabricated with deposition techniques.
