LASIK eye surgery uses pulses of laser light to shave off tissue
from the cornea, reshaping it. A typical LASIK laser emits a
1.1-mm-diameter laser beam with a wavelength of 193 nm . Each laser
pulse lasts 19 ns and contains 1.0 mJ of light energy. What is the
power of one laser pulse? During the very brief time of the pulse,
what is the intensity of the light wave?
