Potential energy and waves

A pulsed laser produces brief bursts of light. One such laser emits pulses that carry 0.350J of energy but last only 225fs.

a) What is the average power during one of these pulses?
b) Assuming the energy is emitted in a cylindrical beam of light 2.00mm in diameter, calculate the average intensity of one of the pulses?
c) What is the rms electrical field in the pulse?


Solution Summary

This solution solves three physics questions addressing average power, pulsed lasers, average intensity and rms electrical field
