Nichia produce 30 mW violet lasers (Asia News)
Nichia is moving its NLHV3000 series of high-power violet laser diodes into volume production. These devices have a peak wavelength of 405 nm and a maximum optical output power of 30 mW, and are intended to increase the storage capacity of DVD players. The shorter wavelength produced by InGaN contributes to the five-fold increase in data storage capacity, from the current 4.7 gigabytes to more than 20 gigabytes, in next-generation DVDs. Also, the increased optical power output of the NLHV3000 series enables the laser to write data as well as just reading the discs.
