Abstract
Uncertainties in the frequency parameters of a frequency comb laser, causes it to represent a mixed quantum state. The formulation of such a quantum state is compounded by the fact that it contains both particle-number degrees of freedom and temporal degrees of freedom. Here we develop a formalism in terms of which such a mixed quantum state can be expressed. For this purpose we also need to compute the expression for the power spectral density of the frequency comb laser. We do so by taking the uncertainties in the frequency parameters into account.
