Re: CREE - blue and blue This might be elementary for most, but just to clear up any possible confusion, when discussing CREE Blue LEDs and Blue Lasers are two separate and distinct items. Chips for Blue LEDs are being produced and sold now and Blue LEDs are in use in a variety of applications as noted on this thread - dashboards, brake lights etc. Blue Lasers are still in the lab. Lasers are use in CDs and DVDs. These machines use red lasers. Blue is better because it has a shorter wavelength, and that means that more information can be encoded and subsequently read in a space. So a CD set for one of Bruce's operas that now comes in a box with 3 CDs will be able to be recorded on just one CD. Or all three Godfather movies may fit on one DVD. (man, life is going to be good this millenium). CREE expects actual products that use blue lasers may be two years away. Other, much larger companies, such as Xerox and Sony and HP are also said to be working on blue lasers. StockHawk
