  • 3 Approaches to Using High Power Diode Laser to Join Thermoplastics (.pdf)
    them to be used to produce a controlled melt, or welding, of thermoplastics. Weld lines as narrow 0.1 mm (0.004 in.) have been achieved using diode laser welding systems. This paper reviews the capabilities of the diode laser welding process, and expands on three methods of delivering the diode laser
  • Frequently Asked Questions about Laser Diode Products
    All of Power Technology's systems are linearly polarized. Index guided diodes typically have a polarization ratio between 50:1 and 100:1. For wide stripe diodes, the polarization ratio is typically 30:1 or greater. Our diode-pumped Nd:YAG systems have a ratio of 100:1. Technical Support For Laser
  • Near Field Imaging of a Laser Diode Using Scanning Method
    This application note describes the result of an experiment performed on near field imaging of a laser diode emission pattern at the output facet. The purpose of the experiment was to provide a proof-of-concept system for the near field measurement of a high-power laser diode bar. The target
  • Analog and Digital Modulation of LQx and DLx Series Laser Diode Modules
    The LQx series Fabry-Perot laser diode modules offers the most precise temperature control available from Newport Corporation. The DLx Series Distributed Feedback (DFB) Laser Source modules offer exceptionally stable wavelength and narrow spectral width. The LQC and the DLC series represent laser
  • Single Longitudinal Mode Blue-Violet Laser Diode for Data Storage
    blue-violet laser diode source with a long coherence length and some level of wavelength tuning. Prior approaches, such as external cavities with diffraction gratings [1], have been used to generate single longitudinal mode tunable lasers near 405 nm. Such cavities require a very low reflectivity
  • Laser Line Scanning (.pdf)
    Laser line scanning is ideal for non-contact measurement applications - including inspection, cloudto- CAD comparison, rapid prototyping, reverse engineering, and 3D modeling. Laser line probes use a triangulation process to find the position of objects in space. A high performance laser diode
  • Comparison of diode-side-pumped
    by. changing of laser diode temperature: for temperature 15 ◦C laser diode operates at at 803 nm, wavelength 808 nm. corresponds with temperature 35 ◦C. The line-width of emitted radiation was ∼ 3 nm. 2.3. Laser Oscillator. The side-pumped trigonal crystals were for most cases tested in simple semi-concave
  • High-Performance Wavelength-Locked Diode Lasers (.pdf)
    Rapidly maturing industrial laser applications are placing ever-tighter constraints on spectral width and wavelength emission stability over varying operating temperatures of high power diode pump sources. For example, improved power scalng and efficiency can be achieved by pumping the narrow upper
