The Texas Petawatt Laser

Posted by kdawson on from the you-can-pet-a-dog-or-you-can-pet-a-cat dept.

Roland Piquepaille notes the hype surrounding what the University of Texas at Austin is calling the world's most powerful laser. During a tenth of a femtosecond this laser is 2,000 times more powerful than all the power plants in the US, and is brighter than sunlight on the surface of the Sun. On his own blog Roland points out that UT's is not the first petawatt laser; that distinction belongs to a system installed at Lawrence Livermore National Laboratory in 1996.

    Will this laser have to be attached to significantly more powerful sharks?

      Wouldn't firing this laser underwater make the water uncomfortably hot? Please people, think of the sharks!

      Bah - who needs sharks... They will just install them in military jets for when they need a LOT of popcorn...

      "Btw, for the same reason, this type of laser is completely useless as a weapon."

      Thanks. Another slashdotter crushes another one of my hopes and dreams. Jerk :(

    It'll never work. There's just no peta tonne shark to put it on.

    It's all good, so long as you remember to shout "BEHOLD! OPTIC BLAST!" before doing it.

    I would be happier if they expressed the power of this laser in the recognized units of "Libraries of Congress" and "football fields".

    To be honest, its hard to get excited about this with the LHC coming online soon.

    True, what's the most this laser could do, cut the Earth in half? Pretty tame compared with the LHC recreating the Big Bang and destroying the universe as we know it.
