QUESTION
A 20 MW laser is outfitted with a polarizer. The laser passes through a second polarizer that is oriented such that it’s axis of polarization is rotated 60o from the axis of polarization of the first polarizer. The laser has a beam divergence, which is the angle that the beam sweeps, of 0.002 radians, and is incident on a screen located a distance of 1000 m away.Using the maximum amount of wire for the coils, how many turns will your primary coil have.
