  • Laser Marking Guide (.pdf)
    to 10 billionths of a second, pulse frequencies up to 100kHz and peak powers up to 100kW. This provides the solid state laser with unique marking characteristics that produce contrasting marks with minimized thermal input. The generation of a laser beam is essentially a three step process that occurs
  • The Progress of Industrial Laser Marking (.pdf)
    in the last several years. Laser markers are now being designed for specific purposes according to wavelength, beam spot diameter, pulse width and frequency. Not only has the technology advanced significantly, but the number of uses for laser marking has spread into nearly every sector of manufacturing.
  • The Big Three in Metal Marking - Applications for Etching, Polishing and Annealing (.pdf)
    by 12-inch marking area, state-of-the art fiber laser technology with flying optics beam delivery to create a system that is economical, easy to use, and advantageous over traditional Nd: YAG galvo based beam delivery systems. The FiberMark is also unique in that it is the only system of its kind
  • What is a MOPA Laser and What is it Used For?
    The term MOPA is an abbreviation for Master Oscillator Power Amplifier. The master oscillator produces the beam while the optical amplifier is used for boosting the output power.MOPA lasers (like Y.0201) are optimally suited for marking naturally and colored anodized aluminum to create black
  • Can a Fiber Laser Engrave Wood?
    If you're looking for a powerful technology that can be used to create clean, fast, high-contrast permanent marks for identification and traceability, fiber laser engraving machines or a compact laser workstation might be the way to go. Their high peak power and superior beam quality make them
  • F-Theta Lenses: A Comprehensive Overview
    F-Theta lenses, also known as flat-field lenses or scan lenses, are specially designed lenses used in applications that require precise control of light, such as laser marking, engraving, and cutting. These lenses transform the incoming beam path into a straight line to provide a consistent beam
  • Choosing the Right Galvanometer and Servo for the Job
    to describe a variety of motions across wide angles. This has enabled new levels of performance in laser marking and other material processing applications, via drilling, highresolution print and imaging applications, DNA analysis and drug discovery systems, and low cost biomedical systems that bring
