Lasik eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. a typical lasik laser emits a 1.0-mm-diameter laser beam with a wavelength of 193 nm. each laser pulse lasts 20 ns and contains 2.0 mj of light energy.
part a: what is the power of one laser pulse?
part b: during the very brief time of the pulse, what is the intensity of the light wave?
