Finally, a True Green Laser

dusty writes "Remember those green lasers from Star Wars? Turns out that faking green lasers has been easy for years, but making true green laser diodes has been the stuff of science fiction. Until recently, that is. Now researchers from Japan have created the world's first true green laser diode. Until now, only red and blue laser diodes were available, and now with the addition of green, new TVs and projectors that are more efficient can be produced. And if you were wondering how green lasers pointers are already produced, it is a hack that involved doubling the frequency of an infrared laser. The new true green laser diodes have much higher efficiency than the current 6%, leading many to expect big time laser display breakthroughs in the near future. Ars Technica has a well-written article on this breakthrough."

    The end result in both cases though is == "Stupid Fuck".

    Why is it so hard to only have politicians for a few years, then have them go away?

    No! No more frickin sharks with frickin lasers jokes. We can't have a slashdot story even remotely related to lasers (or sharks) without this comment.

    No personal offense to you, Mr. Sweeney. It just stopped being funny after the first 30 laser stories for me. Maybe any story with "laser" in the title should have a comment auto-posted that says:

    "[insert generic reference to Austin Powers here]. You may all continue with meaningful or humorous dialogue now."

    Come to think of it, we should do this with every knee-jerk comment that will inevitably be modded up to +5 Funny. Or maybe change them to +5 Tiresome and Predictable.
