Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time. These devices are called pulsed lasers and can be used to ignite nuclear fusion, for example. Consider a pulsed laser that produces an electromagnetic wave with a maximum electric field strength of 2.73 × 1011 V/m for a duration of 1.00 ns. What energy does it deliver on a 1.00 mm² area? Assume, for simplicity, that the sinusoidal electric field has the same amplitude (i.e., constant maximum electric field strength) throughout the duration of the pulse.
