The National Ignition Facility (NIF), which became operational in 2009, uses 192 laser beams to stimulate nuclear fusion in a deuterium-tritium fuel pellet. The net output of the lasers is 1.8 MJ of 351-nm light, delivered in a brief (4.0-ns) pulse. (a) What is the average power delivered during the pulse? Compare your answer with the average power consumption in the United States, about 3 x 1012 W. (b) How many photons are produced in each pulse?
