  • Driving Diode Lasers
    Driving diode lasers loses much of its mystery if you observe a few simple rules based on their properties. Below its threshold current, a diode laser emits LED light with spontaneous emission only. At the threshold current and above, it begins to generate laser light, and the optical output power
  • 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
  • Phase Conjugate Laser Optics - Preface
    years are the increase in laser output power or. pulse energy by orders of magnitude due to the introduction of the. diode pumping of the gain media. This technology also led to a. remarkable improvement of the electrical to optical efficiency as. well as compactness and reliability of the sources

    , and bar coding parts. In addition, laser systems can also precisely cut and shape thin materials such as wire and stencils. Below are descriptions of several laser systems including diode-pumped laser markers, linear stages for laser positioning, and polymer stencil manufacturing systems
  • To infinity ... and beyond!
    Physics laboratory. Snowstar has chosen a 60-W nLight laser diode from nLight Corp., Vancouver, Wash. The diode laser is powered by a 75-A laser power supply from Lumina Power Inc., Peabody, Mass. Results are confidential at this stage of design, but the team sees nLight diodes as likely candidates
  • Analysis and Design of Vertical Cavity Surface Emitting Lasers - Preface
    that the computational efficiency can be improved. However, this approach will not provide detailed information on heat distribution. Detailed heat distribution inside the laser cavity is studied by solving the heat equation numerically. In this case, the influence of thermal lensing on the optical field profile
  • Medical Device Link .
    in modifying surfaces of polymers. For example, the compact and energy efficient diode and fibre lasers enable higher process efficiencies and are relatively easy to integrate into manufacturing lines. New types of beam-forming optics and beam-monitoring systems allow the process to be controlled
  • Efficient green-light generation from waveguide crystal
    lasers have yet to. be demonstrated. Second-harmonic generation (SHG) of light from an. infrared laser diode in a waveguide crystal is a promising alternative. approach to green-light generation with minimal sacrifice in terms of. wallplug efficiency and footprint. A configuration consisting
  • OH Emission Spectra of Hybrid Rocket Motors Using
    Our goal is development of diode laser sensors that monitor hybrid rocket motor. emissions in the near-infrared. Quantities desired from the measurements are temperature,. molecule number density, pressure and velocity. Targeted species include carbon dioxide,. water and OH radicals. The measuring
