Livermore National Lab Creates World's Strongest Laser? July 2012
Uh, should we be worried about this? The Lawrence Livermore National Lab just shot a 500 terrawatt laser some time in July 2012. How strong is that? It's 500 terrawatts, 100 times more powerful than any other laser on the planet.
The folks at the Lawrence Livermore National Lab spent 15 years on their laser. It essentially is the focused beam of 192 lasers. Essentially, the laser gets its power through fusion. This FOX News story provides a good synopsis.
Let's just hope the Livermore folks use their powers for good, not evil.
