With the coming of very cheap blue laser diodes, PCB fabrication has become increasingly interesting. Instead of making a photoresist, placing it over a piece of pre-sensitized copper clad board ...

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 ...

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.

Blue Laser Diodes are expected to experience the highest CAGR from 2024 to 2032 due to their shorter wavelength, enabling high data storage density and render more accuracy in both manufacturing ...

“We report on the first visible orange samarium laser directly pumped by a blue 465 nm GaN semiconductor laser diode,” wrote Alain Braud and colleagues in the abstract of the paper. “Our work ...

It allows high resolution measurements of extremely small objects. The scanner is built with a blue-violet laser diode and projects a 10 mm long laser line at a profile resolution of 1280 measuring ...
