Homogeneous Intensity within the Rayleigh Length and Enhanced Depth of Focus for Gaussian Beams Open
The smallest width of a Gaussian beam at the focal plane is called waist and is only limited by the diffraction limit of the light. The waist determines the Rayleigh length which is the distance from the waist at which the width of the Gau…

Design and Manufacturing Method of Fundamental Beam Mode Shaper for Adapted Laser Beam Profile in Laser Material Processing Open
Many laser material processing applications require an optimized beam profile, e.g., ring shape or Top-Hat profiles with homogeneous intensity distribution. In this study, we show a beam shaping concept leading to a phase shifting element …

Beam Shaping Optics for Process Acceleration Open
Within in the last years the average power of industrial pulsed laser systems is continuously increasing. However one can often not make efficient use of the available power, since the laser process limits the pulse energy which can be app…
