Cavity dispersion equation Deltalambda approximately Deltatheta( partial differentialtheta/ partial differentiallambda)(-1): a note on its origin.
A simple derivation of the cavity dispersion equation for high-gain pulsed lasers, Deltalambda approximately Deltatheta/ partial differentiallambda)(-1), is provided by using Dirac's notation for probability amplitudes as applied to the analysis of dispersive cavities.
