Blue-violet power diode outputs 210mW

Hamburg, Germany: Next month, Sharp will start production of what it claims is the most powerful blue-violet laser diode. Dubbed the GH04P21A2G, the diode features a pulsed optical output of 210mW. Consequently, it will enable high-speed 6X recording on next-generation, dual-layer blu-ray discs as well as HD-DVDs.

This diode uses the crystal growth technology developed for infrared, red, and blue-violet low-power laser diodes. It’s expected to have a service life of 10,000 hours.
