In LASIK surgery, a laser is used to reshape the cornea of the eye to improve vision. The laser produces extremely short pulses of light, each containing 1.0 mJ of energy.
Required:
a. In each pulse there are 9.7?1014 photons. What is the wavelength of the laser?
b. Each pulse lasts only 20 ns. What is the average power delivered to the eye during a pulse?
