    Because of a problem with heat cracking the conventional blue lasers used for next generation DVDs a new method using water has been developed. This should reduce costs, which have been high during early production development.

    Liquids, however, don't crack. Enter the world's first water-based blue laser. Researchers at BlackLight Power heated water vapor with microwaves to generate energized hydrogen atoms which emit multispectrum light rays, including infrared, blue and violet. A prototype blue laser device is expected by the end of the year.
