hello,
I am a student and i m doing my Masters in Electrical Eng. at San Jose State uni, CA.
I want to learn abt blue laser diode. I have no knowledge abt it. Can anyone provide me with the any stuff, tutorials, theory or anything, where i can know abt blue laser diode operation, its applications, current tradeoffs,and future possibilities.

U can email me at my id: hardiksujal@yahoo.com

Iam also an student from Mexico and i am very intrested in the information of the diode propierties and its beam, and in particular i have a particular technical cuestion about the beam, why is it the beam blue instead of red?

the wavelenght of the blue is smaller 405nm than the red 633nm.
So you can write more data on a disk but blue diode not easy to build and are at the moment quite expensive
Is Someone know a price (nichia sanyo)?

Ya, what he said. narrower beam means that it can read smaller pits or whatever little storage thingies the disc uses, greatly increasing the amount of data a disc can hold. (increases the disc's data density).

I also hear that they use a new "ridge" system with lines or something in the disc to provide extra data. *shrugs*
