Frequency response of a Fabry-Perot cavity excited by a frequency modulated stochastic laser field

Summary form only given. Frequency modulated laser light, when synchronously detected after reflection from a Fabry-Perot cavity, give rise to well known discrimination curves, if the source is tuned across the resonance. In lineshape calculations, the laser field is normally assumed to be monochromatic. Several different models describe the laser phase/frequency noise, namely phase diffusion model (PDM), FM or phase modulation from a band-limited Gaussian noise (GNM), and a generalized phase jump model (PJM). Our work deals with the analysis of the dependence of the static frequency response on the parameters pertinent to each model. Moreover, in the PSD case, approximate expressions for the intensity spectrum are given.
