Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. They are used to ignite nuclear fusion, for example. Such a laser may produce an electromagnetic wave with a maximum electric field strength of 1.11 ✕ 1011 V/m for a time of 1.10 ns. What is the maximum magnetic field strength in the wave? What is the intensity of the beam? What energy does it deliver on a 1.17 mm2 area?
