Lasik eye surgery utilizes pulses of laser light to shave, Ask an Expert

Academics

LASIK eye surgery utilizes pulses of laser light to shave off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.4-mm-diameter laser beam with a wavelength of 193nm. Each laser pulse lasts 12ns and contains 1.0mJ of light energy

Part A

What is the power of one laser pulse?

Part B

Through the very brief time of the pulse, what is the intensity of the light wave?
