Question:

A pulsed laser produces brief bursts of light. One such laser emits pulses that carry 0.350 J of energy but last only 225 fs.
(a) What is the average power during one of these pulses?
(b) Assuming the energy is emitted in a cylindrical beam of light 2.00 mm in diameter calculate the average intensity of this laser beam.
(c) What is the rms electric field in this wave?
