Sony Releases 400mW-output Blue-violet Laser Diode for Blu-ray Disc

Sony Corp released the “SLD3237VF,” a new blue-violet laser diode expected to be used for recording and playing Blu-ray discs.

It features a pulsed output as high as 400mW and supports “BDXL,” a new standard for large-capacity Blu-ray discs.

According to Sony, the SLD3237VF is the industry’s first blue-violet laser diode that has an output of 400mW or higher. The high output allows to use a wider variety of optical compon
ents such as lenses and prisms and, thus, to design hardware more freely.
