However, the nature of resonance is the same for all these laser structures. In theory, the resonance mode of a cavity depends on its optical length (L), and the mode is fitted using the following equation: mλ = L (1) mλ = L ( 1) For F-P mode cavities, L = 2neffl L = 2 n e f. For WGM cavities, L = πneffD L = π n e f D.
