The company where you work has obtained and stored five lasers in a supply room. You have been asked to determine the intensity of the electromagnetic radiation produced by each laser. The lasers are marked with specifications, but unfortunately different information is given for each laser: Laser A: power = 2.6 W; diameter of cylindrical beam = 2.6 mm Laser B: amplitude of electric field = 480 V/m Laser C: amplitude of magnetic field = 8.7 x 10-6 T Laser D: diameter of cylindrical beam = 1.8 mm; force on totally reflecting surface = 6.0 x 10-8 N Laser E: average energy density in beam = 3.0 x 10-7 J/m3 Calculate the intensity for each laser, and rank the lasers in order of increasing intensity. Assume that the laser beams have uniform intensity distributions over their cross sections.
A high-energy pulsed laser emits a 1.0ns Long pulse of an average power 2.2x10^11 W. The beam is nearly a cylinder 2.2x10^-3 m in radius. Determine the energy delivered in each pulse and the rms value of the electric field
