The National Ignition Facility at Lawrence Livermore National Laboratory initiates nuclear fusion by converging 192 laser beams on a deuterium-tritium target. Each beam has a square cross section 38 cm on a side, and each beam delivers 10.0 kJ of energy in 20.0 ns.
Required:
a. Find the peak electric field in each laser beam.
b. Find the peak magnetic field in each laser beam.
c. Find the combined power of all 192 laser beams while they're firing.
d. Determine the ratio of the combined power of all 192 laser beam to the humankind's energy consumption rate of about 16 TW.
