Ultrafast blue-violet pulsed semiconductor laser, Sony Corporation and Tohoku University.
Just when we assume technological standards for commercial media have stabilized, we have a surprise in store. Those still contemplating the switch from DVDs to Blu-ray, for example, will have another format to consider soon.
Researchers at Sony and Tohoku University have recently created a new blue-violet ultrafast pulsed semiconductor laser, with an immediate application in disk storage. Capable of producing three-picosecond-long optical pulses, the laser has 100 times the output value of existing blue-violet pulse semiconductor lasers.
According to the Yomiuri Shinbun, this advancement will give discs 20 times the capacity of Blu-ray technology, meaning that future discs could fit over 50 movies of the same quality level. No doubt, this achievement will drive even higher resolution standards in video formats.
