  • Femtosecond Pulsed Laser Deposition Examples
    Femtosecond lasers have significant advantages for pulsed laser deposition applications. Due to the high peak power and short pulse duration, femtosecond laser pulses result in clean ablation with minimal thermal damage, shock-affected-zone, debris, or recast. The unique physics behind
  • Synthesis of (SrLaF)FeAs superconducting films by pulsed laser deposition
    We have tried to prepare superconducting (SrLaF)FeAs thin films by the photo excited pulsed laser deposition (PE-PLD). The. excitation of As Sr and La atoms are observed in the luminescence spectra of the ablation plum during the deposition. The peak. intensities due to above excitations become
  • Suitability of Materials for Pulsed Laser Welding (.pdf)
    Material Coatings/Platings: These can have an affect on weld quality, and generally require testing as case specific. One example of coating sensitivity is gold/nickel or nickel coatings. Coating should be electrolytic, avoiding excessive phosphorus that creates increased cracking susceptibility,
  • High Density Pulsed Laser Diode Arrays for SSL Pumping (.pdf)
    This work contains an overview of the manufacturing process, as well as representative data for 5-, 10-, and 20-bar arrays. Near-field and power vs. current data is presented in each case. Power densities approaching 15 kW/cm2 are presented. In addition, power and wavelength are presented as a
  • Thermographic Analysis of Laser Pulsed Water Jets (.pdf)
    . The ablation performance of a water jet can be enhanced by introducing a dynamic component to the jet. To achieve a high energy droplet water stream at defined impact rates, laser radiation was used to introduce steam bubbles in close proximity to the water nozzle, generating a pulsed disruption of the jet.
  • Laser Drilling Tablets for Use in Osmotic and Other Novel Drug Delivery Systems
    range of commercially available CO lasers, offering output powers from a few watts to multi-kilowatts. Furthermore, some CO lasers operate in a continuous wave (CW) mode, while others are pulsed. A CW laser produces an uninterrupted beam of light, while a pulsed laser emits a stream of very short
  • Pulsed UV Curing for Blue Laser Media
    Among the many new challenges for manufacturers of third generation media are the issues of bonding and. curing; pulsed UV curing may be an effective solution.
  • Interfacing Pulsed Power Systems to Switching Power Supplies
    range from large single shot capacitor banks to high pulse rate laser systems. This paper will discuss issues in interfacing switching power supplies to pulsed power systems. Simple protection networks can be used to avoid damage to power supplies in normal operation and in fault situations. Design
