Some of the most powerful lasers in the world are used in nuclear fusion experiments. The NOVA laser produced 40.0 kJ of energy in a pulse that lasted 2.50 ns, and the NIF laser produces a 20.0-ns pulse with 4.20 MJ of energy.
(a) Which laser produces more energy in each pulse?
(b) Which laser produces the greater average power during each pulse?
(c) If the beam diameters are the same, which laser produces the greater average intensity?
