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.

If you’ve played around with laser diodes that you’ve scavenged from old equipment, you know that it can be a hit-or-miss proposition. (And if you haven’t, what are you waiting fo… ...

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 ...
