Laser Systems Get Boost with Top Hat Radiance Distribution
Laser systems, widely used in industry and research, face a challenge: most have a non-uniform Gaussian radiance distribution, leading to light loss. However, companies like 3SAE Technologies Inc. and Jenoptik are addressing this issue with innovative solutions.
These companies produce diffractive optical elements (DOEs), specifically designed to reshape Gaussian beam profiles into Top Hat profiles. This conversion, achieved using a diffractive beam shaper, results in a more efficient radiance distribution with constant energy density and hard edges.
In materials processing, laser beams are commonly used for ablation or marking in metals. A Top Hat distribution would significantly improve efficiency in these applications, reducing waste and enhancing precision.
By employing DOEs to achieve Top Hat radiance distributions, laser systems can operate more efficiently. This benefits various industries and research fields, particularly in materials processing, where precise and waste-free laser applications are crucial.
