Diffractive beam shapers are used to modify the intensity and phase profile of spatially coherent lasers, allowing a better control of the output beam.
These optical elements are most commonly used for the optimization of energy distribution in laser applications where the correction of non-uniform and Gaussian beam profiles can lead to better over all efficiency and performance.
Jenoptik designs high performance beam shapers to create uniform top-hat, circular, or rectangular profiles, as well as custom geometries. These beam shapers are designed to work with single spatial mode input beams. For multimode laser beams, refractive or diffractive diffusers and homogenizers can also be designed.
