each pulse produced by an argon-fluoride excimer laser used in PRK and LASIK ophthalmic surgery lasts only 10.0ns but delivers an energy of 2.50mJ. (a) what is the power produced during each pulse? (b) if the beam has a diameter of 0.850mm, what is the average instenisty of the beam during each pulse? (c) if the laser emits 55 pulses per second, what is the average power it generates?
