We reckon that 20 W effective power diodes are not that ... close to the potential of the blue box “40 W but actually 35 W but actually way less” K40 laser cutters we cherish.

The history of the blue-light laser diode is closely linked to that of the blue LED. Early commercial semiconductor light sources were made using semiconductor compounds gallium arsenide or ...

blue lasers became commercially available in 2001. Blue diode lasers allow for smaller pits to be used in optical discs (CD-ROMs use 780 nm pits; DVDs are 630 nm). Blue light-emitting diodes (LEDs ...

Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, and laser-induced chemical liquid phase deposition onto glass. Whoo! I'm ...

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 ...
