McCumber Theory

A theory applied to Absorption and emission properties of Laser Gain media, in particular to solid-state media with Stark level splitting.

In the 1960s, Dean E. McCumber at Bell Laboratories worked out a detailed theory, now called the McCumber theory, to explore the quantitative relations between various optical properties of laser gain media such as molecular gases but also rare-earth-doped or transition-metal-doped gain media.
