The Most powerful laser in the world


April 2008

The Texas Petawatt laser reached greater than one petawatt of laser power on Monday , March 31, 2008 making it the highest powered laser in the world, Todd Ditmire, a physicist at The University of Texas at Austin, said.

It has the power output of more than 2,000 times the output of all power plants in the United States. (A petawatt is one quadrillion watts.) The laser is brighter than sunlight on the surface of the sun, but it only lasts for an instant, a 10th of a trillionth of a second (0.0000000000001 second).

Ditmire and his colleagues at the Texas Center for High-Intensity Laser Science will use the laser to create and study matter at some of the most extreme conditions in the universe, including gases at temperatures greater than those in the sun and solids at pressures of many billions of atmospheres.

This will allow them to explore many astronomical phenomena in miniature. They will create mini-supernovas, tabletop stars and very high-density plasmas that mimic exotic stellar objects known as brown dwarfs.

The Laser was built with funding provided by the National Nuclear Security Administration, an agency within the U. S. Department of Energy.
