…also incorporates Coherent’s unique, patented SmartWeld™ technology for producing complex “beam wobble” patterns, including even circular and zigzag paths. SmartWeld™ enables bridging of larger gap widths which relaxes fit up tolerances, increases process flexibility, and delivers welds with higher…

…a higher thickness to width aspect ratio. High beam intensities heat the material upon evaporation temperature resulting in a deep capillary called a keyhole. Heat conduction welding is applicable for sheet metal up to a material thickness of approximately 2 mm. A laser beam, focused on the seam,…

…ferroelectrics and “high k” gate resistors, semiconductor alloys, carbon nano-tubes, and more. Although visible or IR laser beams have been used for PLD applications, UV beams are now most commonly employed. Among UV pulsed lasers, excimer lasers provide a variety of short wavelengths combined with…

…Myopia, astigmatism, and hyperopia can all be treated effectively with the non-thermally damaging and precisely controllable ArF excimer laser beam. This technique has already helped millions of people since the early 1990s to enjoy life without glasses or contact lenses. Coherent is the leading…

laser beams cannot be defined as easily as the
dimensions of hard physical objects. A good
example would be the task of measuring the
width of soft cotton balls using vernier
callipers. A commonly used definition of beam
width is the width at which the beam intensity…

…crucial. Beam Diameter (Radius, Width) The beam diameter (generally defined as twice the beam radius, no matter what the particular definition of the beam radius is) is the most important propagation-related attribute of a laser beam. In case of a perfect top-hat (or flat-top) profile the beam

…The Width Adjust Factor multiplies the measured width between
clip levels to give beam width (2W). Minimum value is 0.20.
Maximum value is 20.00.
The default setting for this parameter is 16.0%, 84.0% and 2.00. This
setting will return a beam width equal to 1/e2 if the beam is a…
