Ever wonder why projector systems and televisions doesn’t use laser illumination? It isn’t for safety reasons, and it isn’t for efficiency reasons—laser diodes have efficiencies ranging from 30 to 50 ...

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 ...

Semiconductors can generate laser light in all colors except one. But new techniques for growing laser diodes could soon make brilliant full-spectrum displays a reality On a rainy Saturday morning in ...

Tell us a bit about green beam lasers. How are they different? Red beam line lasers have been standard on the jobsite for years, but newer green beam lasers are up to four times brighter than red ...
