The NNSA’s National Ignition Facility (NIF) surpassed a critical
milestone in its efforts to meet one of modern science's
greatest challenges: achieving fusion ignition and energy gain
in a laboratory setting. NIF's 192 lasers fired in perfect
unison, delivering a record 1.875 million joules (MJ) of
ultraviolet laser light to the facility's target chamber center.
This historic laser shot involved a shaped pulse of energy 23
billionths of a second long that generated 411 trillion watts
(TW) of peak power (1,000 times more than the United States uses
at any instant in time). The ultraviolet energy produced by NIF
(after conversion from the original infrared laser pulse to the
final ultraviolet light) was 2.03 MJ before passing through
diagnostic instruments and other optics on the way to the target
chamber. As a result, NIF is now the world's first 2 MJ
ultraviolet laser, generating nearly 100 times more energy than
any other laser in operation. To read more about the March 15
