We’ve used “ Sam’s Laser Diode Test Supply 1 ” for years, and we love it, but a pulsed laser tester would be a cool addition to the lab. What to do with your junk DVD-ROM laser?

Testing laser diodes that exist on a wafer or in die form presents a challenge. These devices lack TECs, so maintaining a constant, controlled temperature proves impractical, if not impossible. To ...

How it Works? The most common laser diode generates semiconductor or injection laser. In these lasers, a population of Inversion Electrons is produced by applying a voltage across its p-n junction.

This feature gets even more important when manufacturing is shoddy enough that the three key components—laser diode, frequency shifter, and SHG material—aren't aligned properly.

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is ...

Coherent opens lab to test new laser diode applications 17 Jun 2002 Coherent's Semiconductor Group (CSG) has opened a new commercial applications laboratory to enable customers to see how Coherent's ...

The fruit of a collaboration with Labsphere, the 2500INT is a custom-designed integrating sphere optical head that facilitates direct optical measurement of laser diode output power when used with ...

Ever wonder why projector systems and televisions doesn't use laser illumination? It isn't for safety reasons, and it isn't for efficiency reasons—laser diodes have efficiencies ranging from 30 ...
