I am far from an expert in the subject but I think that the usefulness of the blue laser may relate to the fact that as light waves go across the color spectrum from blue to red they become "longer" - that is a blue light wave is much shorter that a red light wave. Because of the shorter wavelength there are more blue light waves in any given unit of time than red light waves during the same interval - which makes the blue wavelength laser much more efficient than the commonly used red wavelength laser for reading from a CD-ROM, for example. Hopefully some of the more scientifically inclined on this thread can expand on this (or tell me if I'm all wet)!
