Olching, Germany - Laser Components announces distribution of Holo/OR's new donut-shaped diffractive optical vortex element (DOE) with a square outside profile.

The outside profile is square, while the inside is round. The technical challenges to achieving a square outer cross section were enormous. These elements make it possible to achieve homogeneous material removal in laser material processing.

Vortex DOEs are enjoying increased popularity. These components put very few demands on the laser beam and on the distance to the working area. Another advantage of these components is the intensity distribution of the laser beam: A laser beam features the highest beam intensity at its center. The Vortex element "redirects" the power to the edges to achieve a higher efficiency of the overall system.
