Abstract: Two derivations of the fundamental laser linewidth are presented that have been used successfully in introductory courses. The cause of the finite linewidth is identified with phase fluctuations in the electric field due to spontaneous emission. A factor of 2 discrepancy between the energy and field analyses is explained. A number of ”back-of-the-envelope” relationships are derived that have proven useful in teaching this subject.
