A set of improved Langevin rate equations for external-cavity semiconductor lasers which can be used to solve transient as well as steady-state problems is derived. A simple relationship among chirp reduction, line narrowing and dynamic stability is given. An experiment on an external-coupled-cavity semiconductor laser consisting of a 1.3- mu m buried-heterostructure laser diode with an antireflection (AR)-coated facet and a 4-mm GRIN rod is reported. Because of its strong optical feedback, it provides a stable single mode, which is not sensitive to the environmental perturbations. This agrees with the theoretical results. No mode jumping occurred during 12 h continuous observation.>
