Limits imposed by spatial hole burning on the single-mode operation of standing-wave laser cavities.
A simple formula is derived that gives the ratio of the maximum single-longitudinal-mode inversion density to the threshold inversion density for a standing-wave laser in terms of the cavity geometry and well-known material parameters. This formula can be used as a guideline in the design of single-frequency lasers.
