Transforming Multi-Mode Laser Beam into Narrow Ring
Transforming the beam of a highly multi-mode laser into a narrow ring (annular shape) with almost single mode diffraction-limited ring width is a potentially useful technique for certain material processing applications, such as drilling and cutting.
Holo/Or has published an experimental demonstration of their unique diffractive method of doing this transformation.
