SDL's blue laser, used for fiber optic applications, isn't a "pure" blue laser. It operates at a wavelength of somewhere around 1300-1650 nanometers. The "pure" blue laser that Cree, Nichia, and the rest are working on works at a wavelength of 490 nanometers. The whole point of developing a blue laser is due to the fact that at 490 nanometers, its wavelength is half that of the 980 nanometer infared lasers currently used for DVDs, printers, scanners, high-resolution TVs, and many other applications, thus allowing for four-times higher resolution, or four times as much data to be stored. Using SDL's 1300-1650 nanometer laser, assuming that it's technologically and economically feasible to do so in such applications, neither of which I'm sure of, would be taking a step in the wrong direction. Hope this helps.
