Find the FSR, \(Q\), and \(F\) of the cavity shown as follows.

Assume that the wavelength of light equals \(1 \mu \mathrm{m}\) and \(\alpha=\) \(0.001 \mathrm{~cm}^{-1}\).
If we have a cavity with a nonuniform index of refraction, then the resonance frequency of the cavity then is given by

and a photon surviving a round trip in the cavity is given by

where \(L_{0}\) is the length of the absorptive medium.
