December 10, 2014 The U.S. Navy says it made a "historic leap" by deploying a laser weapon system for the first time. A video shows the system, based on the USS Ponce in the Persian Gulf, taking target practice.
November 4, 2014 The laser, China said, can destroy small-scale drones flying at a low altitude. The U.S. tested a similar system, last year. It put it aboard a ship in the Persian Gulf.
Physicists put diamonds at the center of this massive laser, to see what would happen.

The National Ignition Facility's 192 laser beams focus onto a tiny target.
February 12, 2014 Researchers from California's Lawrence Livermore National Laboratory say they've figured out how to get their laser to squeeze hydrogen atoms together to make helium atoms, releasing energy in the process. It's an important step in the decades-long quest for fusion energy.

October 26, 2012 The world's most powerful laser beams are going to be built in Europe. Scientists say that a blast from them could destroy nuclear waste in seconds — meaning it wouldn't have to be stored for centuries.
December 13, 2011 A camera that captures images at the rate of one trillion exposures per second is a device with amazing potential, according to researchers at MIT.
