WebJun 10, 2024 · This converts an incident Single-Mode Beam to a flat-top beam. It is used for suppressed taper processing in micro cutting and micro drilling. WebA more sophisticated system employs a wavefront sensor (described below) capable of characterizing the shape of an incident wavefront. A beam splitter is placed in the optical path and used to reflect part of the light onto a wavefront sensor as illustrated in Figure 3b. The information derived from this sensor is used to calculate the shape of the mirror …
WebFor good quality beam shaper performance, the laser output should be Single-Mode (TEM00) with an M 2 value under 1.3. ALL apertures in the beam path must be at least 2x larger than the beam size (1/e 2) on the aperture plane (optimally > 2.5x).These often include mirrors (for beam folding or scanning), beam expanders/ telescopes, and focusing optics … WebMar 15, 1996 · A simple beam-shaping technique is described whereby the output from a highly asymmetric non-diffractionlimited laser source, ...
