"Webwhere the effective mirror reflectivity finesse is given by F R = πR1/2/(1-R). (5) here, R is the mirror reflectivity. While the definition for the reflectivity finesse is ambiguous in the literature, Eq. (5) is presented as an “effective” finesse that is defined by Eq. (3) when the other contributing factors are negligible. " - Reflectivity finesse
