We consider properties of periodic solutions of the differential-delay system, which models a laser with optical feedback. In particular, we describe a set of multipliers for these solutions in the limit of large delay. As a preliminary result, we obtain conditions for stability of an equilibrium of a generic differential-delay system with fixed large delay $tau$. We also show a connection between characteristic roots of the equilibrium and multipliers of the mapping obtained via the formal limit $tautoinfty$.
