Nichia Corporation succeeded in developing high power violet semiconductor laser diodes corresponding to a double-layer disc at more than 12 X record speed/ a quad-layer disc at more than 2 X record speed applied for the next generation DVD recorders.

We confirmed that estimated life time exceeded 10,000 hours and stable operation was achieved for 1000 hours with the condition of 420 mW pulsed operation at 80°Ccase temperature.

The LD market is expected to be dramatically expanded with launching for the next generation DVD market. Nichia Corporation will do the best for the market demands by expanding the production capacity as well as improving the product-quality.

Moreover, we cooperate with all employees focusing on the development of the innovative products, which would contribute to the whole society.
