Required information A laser used in LASIK eye surgery produces 42.0 pulses per second. The wavelength is 193 nm (in air), and each pulse lasts 10.0 ps. The average power emitted by the laser is 107.0 mW and the beam diameter is 0.800 mm. What is the intensity during a pulse?

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?
