The history of the blue-light laser diode is closely linked to that of the ... from a single laser array chip. The next step for Panasonic is to combine the output of many such devices to attain ...

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 ...

Laser diodes are tiny devices containing an active semiconductor medium formed from a p–n junction and are powered by injected electrical current. The semiconductor wafer is produced using ...
