What is the power during one of these pulses

Reference no: EM13313881

Lasers are used extensively in eye surgery to remove unwanted "material" from the eye or reshape the eye's lens. These lasers use pulses of very intense radiation to literally "blast" away material. These pulses are typically 10 ns long (10%u22128 s) and carry an energy of 2.5 mJ each.

(a) What is the power during one of these pulses?

(b) If this energy is delivered to a spot on the eye that is 1.7 mm in diameter, what is the intensity during a pulse?

W/m2

V/m
