  • Fiber Lasers for Hard Disk Texturing (.pdf)
    In today's modern hard disk drives, a controlled magnetic disk texturing is needed to alleviate the problem of "stiction" which occurs when the disk stops spinning and the super-smooth slider comes into contact with the super-smooth disk. A pulsed fiber laser operating at high pulse repetition rate
  • Fiber Laser Marking - Colour Marking

  • Increased Pulsed Amplifier Efficiency by Manipulating the Fiber Dopant Distribution (.pdf)
    power increases [4]. It might then be anticipated that the large peak powers and the presence of nonlinearities in pulsed amplifiers might lead to no benefit to the confined dopant fiber. Here, for the first time, we show that a comparable advantage can be obtained even with pulsed amplifiers
  • Fiber Laser Marking of Plastic: Polycarbonate
    pulsed fiber laser uses a. MOPA (Master Oscillator Power Amplifier). Marks, such as graduated marks, indicating the. architecture, (Fig. 1), which uses a directly. volume of fluid are of prime importance in both. modulated seed laser that is amplified using a. the packaging and medical sectors

  • Application Newsletter-UID Marking Aluminum with the i-Series Fiber Laser
    or dual head configuration. Integrated design with laser, laser control and power supplies are in one housing for each of the two scan heads. UID Marking Application Report: Aluminum samples were processed using a Pulsed fiber laser (1060nm wavelength, 1mJ @ 50kHz, 50W average) through a 160mm F-theta
  • Fiber Laser Welding of Clear Plastics
    to the medical industry is the need to weld clear or light - coloured plastics. Information is presented here for the first time using fiber lasers to weld clear-to-clear plastics. A novel laser source is therefore used in combination with a novel laser welding technique to produce results of real
