Diode lasers (or laser diodes) are semiconductor lasers which use electrical power as an energy source and doped p-n junctions as a gain medium. As discussed in the Lasers Selection Guide, all lasers ...

Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...

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 ...

[Drake Anthony] makes building a cutting laser from a PC look easy, and it seems like it actually is. Almost everything you need can be found in a dead desktop unit. The diode is pulled from a DVD ...

In the image above you can see the silver cylinder which houses the laser diode. It is focusing the ... a 1.5V power source, and a headphone jack. The transmitter is not much more complicated ...

nearly all modern laser pointers use electrically-powered laser diodes as their energy source. The image below shows a deconstructed laser pointer and identifies its main components. In the image, the ...

Due to the external laser source, however, the laser threshold of ... combined the NV diamond with a second laser medium, a ...
