http://www.engadget.com/2009/05/29/worlds-largest-laser-opens-for-business-in-california/ Another day, another laser... well, not so fast. This particular laser just so happens to officially carry the "world's largest title." Built at Lawrence Livermore National Laboratory in Livermore, California, and housed in the National Ignition Facility -- or NIF -- it was completed at the end of March, and has just now been officially dedicated and opened for business. The laser inside the three-football field-sized building will aim to create a "star" on earth by focusing 192 beams at a pea-sized target, generating temperatures over 100 million degrees and pressure over 100 billion times the earth's atmosphere. The process will create nuclear fusion -- the reaction that powers the sun and the stars. it sounds pretty complicated, and we'd hate to be in town if something goes awry, but we're crossing our fingers for the team!
