How Monochromatic Is Laser Light?
Jacobs, Stephen F.
American Journal of Physics, v47 n7 p597-601 Jul 1979
Presents two derivations of the fundamental laser linewidth that have been used successfully in introductory physics courses. The cause of the finite linewidth is identified with phase fluctuations in the electric field due to spontaneous emissions. A factor of 2 discrepancy between the energy and field analysis is explained. (Author/GA)
