Sumitomo Electric and Sony announce powerful true green semiconductor laser diode

News from Sumitomo's and Sony's joint-development of laser diodes:

"Sumitomo Electric Industries, Ltd. and Sony have successfully developed the world’s first*1 semiconductor laser diode with an optical output power of over 100 mW in the true green region at a wavelength of 530 nm. This laser diode can be mounted on laser projectors and many other display devices. The new laser diode features twice the luminosity*2 compared with conventional gallium nitride (GaN) green laser diodes, and a color gamut broadened by 182% based on the NTSC standard (CIE 1976 color gamut)*3. As a result, these significantly improve the performance of laser projectors and other display devices to reproduce vibrant video and images."
