Green is the new green

I was reading up a little about green laser diodes thanks to a news article that came through a professional discussion group, and lo and behold, I just find that Photonics Spotlight (check blog link on right) talking about the same topic.

Seems like periodically, there is a synergy of ideas regarding both fundamental science and applications, a convergence of efforts, a maturing of technology, and one then has the next "surge" in the field.

Of course, for the uninitiated, here green laser diodes refer to the color of light emitted, rather than the environmental aspect of it. But we know that semiconductor based lighting sources are head and shoulders above incandescents and CFLs in efficiency, so they indeed are green.
