We investigate a degenerate optical parametric device with a transversely finite unstable cavity configuration operated below threshold. Using an approximate quantum description in terms of a biorthogonal set of effective cavity-matched modes and their adjoint modes, we predict an intracavity field intensity enhancement by the Petermann excess-noise factor, K . This enhancement is accompanied by a reduction of photon bunching and quadrature squeezing.
