Sharp’s 250mW Blu-ray laser enables 6x recording in laptops

Japan’s Sharp is introducing a new generation of blue-violet laser diodes with output boosted to 250mW, enabling recording on dual-layer Blu-ray discs at 4-6x speeds.

Maintaining the same 3.3mm diameter of its previous package, the new GH04P25A4G is intended for notebook drives. In addition, the new 5.6mm diameter GH04P25A2G is intended for PC drives.

The lasers are shipping now in sample quantities for ¥50,000 (about $462). Mass production should start in April, at a maximum monthly capacity of 700,000 units. Blu-ray drives featuring the new 250mW lasers should enter the market in second-half 2008.
