  • Driving Diode Lasers
    rises steeply with increasing diode operating current. The correlation between the optical output power and the diode current is linear up to the maximum power, called differential efficiency (Figure 1). One crucial figure often overlooked in handling diode lasers is the influence of temperature
  • 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
  • Medical Device Link .
    EQUIPMENT NEWS: Laser Processing and Marking Laser Equipment Makes Its Mark Systems gain in efficiency and precision Once a staple of science fiction, lasers are now a well-established part of medical device manufacturing. Laser marking of plastics and metals is essential for identifying, labeling
  • 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
  • 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
  • Analysis and Design of Vertical Cavity Surface Emitting Lasers - Preface
    , slope efficiency, and output power, all depend on the operating temperature of lasers. Furthermore, the optical behavior of VCSELs is affected by thermal lensing (i.e., self-focusing of transverse modes into the core region of the active layer). Therefore, the thermal properties of VCSELs
  • OH Emission Spectra of Hybrid Rocket Motors Using
    instrumentation will become part of the rocket. motor control system to optimize thrust, fuel efficiency and safety response. To validate OH. radical information gathered from the near-infrared region using diode lasers, studies are. being conducted that measure OH radical emission spectra
