Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core of singlemode fibers.

There’s clearly a demand for this sort of desktop laser, the simplicity of using a diode over a laser tube ... be piped out a nearby window, or connected directly to the optional air filter ...

Could a practical green laser diode finally be within sight? The latest research looks optimistic. Researchers at the Japanese company Nichia have fabricated an InGaN semiconductor laser diode ...

The range includes three new 405-nm laser diodes, which offer 20 mW, 45 mW or 85 mW optical output power. Photonics Products claims this performance represents the highest power available in a ...

After reading tales about cutters of such size going out of alignment when someone as much as walked nearby, he dropped the idea – and equipped the CNC head with a high-power laser diode module ...
