For dry air at a temperature of 0°c and at 1 atm of pressure, electric breakdown occurs when the air is subjected to an electric field with amplitude above about 3.00 mv/m. a high-power laser is shone up into earth's atmosphere, and the laser's associated electric field ionizes the air and turns it into a conducting plasma. assume the conditions of the air are such that an electric field of 3.00 mv/m causes the air to ionize. (a) what will be the intensity (in w/m2) of a laser beam that can produce a field of this magnitude? w/m2 (b) assuming the laser is operating at this maximum intensity, what is the power (in w) delivered in a cylindrical beam with a diameter of d = 4.10 mm? remember that the intensity is defined as power per unit area; solve this relationship for power. w
