Researchers build a 1,000-watt 'super laser'
British and Czech researchers have successfully fired a 1,000-watt 'high peak power laser', claimed to have average power 10 times more than any other of its kind. Although there are a couple of petawatt (15 zeros) lasers in the US and Japan, but they can only fire few times a day producing a lesser 'average power' output, researchers said.
