{\displaystyle c_{0}} ν A exhibits after entering the resonator and accumulating the electric field Constructive interference occurs if the two beams are in phase, leading to resonant enhancement of light inside the resonator.

A the Airy linewidth ( {\displaystyle E_{\text{trans}}} i i {\displaystyle T_{e}=1} {\displaystyle \nu _{q}} < e An optical frequency comb is adopted as the interrogation laser. This approximation of the Airy linewidth, displayed as the red curve in the figure "Lorentzian linewidth and finesse versus Airy linewidth and finesse of a Fabry-Pérot resonator", deviates from the correct curve at low reflectivities and incorrectly does not break down when is displayed as the green curve in the figure "Lorentzian linewidth and finesse versus Airy linewidth and finesse of a Fabry-Pérot resonator". back {\displaystyle A_{\rm {trans}}^{\prime }} {\displaystyle \alpha _{\rm {loss}}} are given by, The electric-field and intensity reflectivities α Δ of frequency. ′ = A arXiv:2005.08822 (2020). Consequently, one can define the Lorentzian finesse of a Fabry-Pérot resonator:[8], It is displayed as the blue line in the figure "The physical meaning of the Lorentzian finesse". q Δ If the Fabry-Perot is configured to give a resolving power of 1E4 on an extended source covering this area, the corresponding velocity resolution on the source is c / R or 30 km/sec. {\displaystyle n} Two beams are shown in the diagram at the right, one of which (T0) is transmitted through the etalon, and the other of which (T1) is reflected twice before being transmitted. {\displaystyle \nu _{q}} accumulates to[8].

Each resonator mode with its mode index F {\displaystyle \nu _{m}} c S The maximum reflectivity is given by. Once the internal resonance enhancement, the generic Airy distribution, is established, all other Airy distributions can be deduced by simple scaling factors. The relationship between θ and θ0 is given by Snell's law: so that the phase difference may be written as, To within a constant multiplicative phase factor, the amplitude of the mth transmitted beam can be written as. 1 Also used to calculate the Airy distribution a e m i t { \displaystyle {.
