Sharp to Begin Volume Production of High-Power Blue-Violet Laser Diodes

Sharp Corporation will begin volume production in May of the High-Power Blue-Violet Laser Diode GH04P21A2G that achieves a power output 1 of 210 mW, the industry’s highest. This device will enable high-speed 6X recording on next-generation dual-layer Blu-ray Discs (BD) and HD-DVDs. As terrestrial digital broadcasting spreads throughout Japan, demand for LCD TVs and HD recorders that support full-spec 1080p HDTV is expanding rapidly. The GH04P21A2G makes full use of crystal growth technology developed for infrared, red, and blue-violet low-power laser diodes.

In addition to a newly developed laser chip with a proprietary facet structure and a high power output of 210 mW that will contribute to high-speed recording for the next generation of DVDs, this current device also features a long service life of 10,000 hours, a level that leads the industry.
