Question: Some lasers emit light in pulses that are only 10 -12 s in duration. The length of such a pulse is (3 10 8

Some lasers emit light in pulses that are only 10^-12 s in duration. The length of such a pulse is (3 × 10⁸ m/s)(10^-12 s) = 3 × 10^-4 m = 0.3 mm. Can pulsed laser light be as monochromatic as light from a laser that emits a steady, continuous beam? Explain.
