Nichia Chemical Puts Blue Laser in Use
November 10, 1997 (TOKYO) -- Nichia Chemical Industries Ltd., a major Japanese manufacturer of fluorescence materials, said it succeeded in continuous-wave operation of a blue-violet laser with a wavelength of about 400nm for more than 10,000 hours.
That can treble the storage capacity of DVDs from the current 4.7GB to 13-14GB in one stroke.
The semiconductor lasers, with 5,000-10,000 hours of continuous-wave operation, are indispensable for CD and DVD drives....

New Blue" Laser Technique Could Soon Be Commercial
Friday December 12 10:16 AM EST
WASHINGTON (Reuters) - A new short wave blue" laser technique will soon be commercially usable and could revolutionize many electronic products, an expert said.
Writing in the journal Science, Gerhard Fasol of Eurotechnology Japan said the technique, first developed in Japan a year ago, is certain to have a large impact on the world as we know it."
The color of laser light corresponds to the size of its wavelength, from blues at the shorter end of the spectrum to red at the long
end.
Different laser devices require different wavelengths. For example, compact disc players currently use infrared lasers but would work better with wavelengths as blue as possible, as would many other electronic products, Fasol said.
Light at the blue end of the spectrum should allow for denser data storage.....
