We discuss similarities and differences of the well-known Lang--Kobayashi delay differential equation model and the traveling wave partial differential equation model. For comparison we locate the continuous wave states in both models and analyze their stability.application/pdfeng510Lang-Kobayashi modelTraveling wave modelfeedback lasercavity modesReport
