In the race to make the first blue-light semiconductor lasers, the lead horse--zinc selenide--has come up slightly lame. Now gallium nitride, a highly touted challenger, has stepped onto the track, as researchers report making the first electrically powered laser from this material. Chip-based blue lasers are expected to be an instant commercial hit, because the short blue wavelengths can be used to pack a lot of data in a very small space.
