Lasers can be constructed to produce an extremely high-intensity electromagnetic wave for a very brief time. Such lasers are 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 0.61 × 1011 V / m for a time of 0.95 ns. a. What is the maximum magnetic field strength in the wave B0, in teslas? b. What is the intensity of the beam I, in watts per square meter? c. How much energy, in kilojoules, does one pulse of the laser beam deliver to a 1.00 mm2 area?
