As cool as lasers are, so far there are precious few commercially available display devices available that use them. That may change with this new green semiconductor laser diode announced by Sony and Sumitomo, capable of the brightness necessary to replace the more expensive light sources used to fill in the middle of the RGB setup. According to the two companies, it's the world's first one capable of over 100mW power at 530nm, which they think will make it a fit for both advanced projectors and compact light projectors
