Q: What is the world's strongest laser?
A: The world's most powerful laser is known officially as the National Ignition Facility. The super laser was created to help keep tabs on the nation's nuclear weapons stockpile while also studying the heavens. It is located at the Lawrence Livermore National Laboratory about 50 miles east of San Francisco.
The NIF is the size of a football field and consists of 192 separate laser beams that travel 1,000 feet in one-thousandth of a second to converge simultaneously on a target the size of a pencil eraser.
