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 ...

Everyone knows that lasers are basically magic, and if you strap a diode laser or two to a lawn mower, it should slice through those pesky blades of grass with zero effort. Cue [Allen Pan]’s ...

[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 ...

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 ...

Researchers from Chiba University have developed a novel calibration-free approach that substantially improves the accuracy ...

Hydrogen, a promising fuel, has extensive applications in many sectors. However, its safe and widespread use necessitates reliable sensing methods. While tunable diode laser absorption spectroscopy ...

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