A theoretical model to describe the behaviour of a frequency modulated (FM) external cavity diode laser (ECDL) has been developed using an iterative travelling wave model, in the strong feedback regime. Experiments have been performed on FM ECDL using two commercial GaAs devices. Results indicated that the frequency of the external cavity longitudinal modes is not pulled to the RF modulation frequency, unlike the behaviour of other FM laser systems. The calculated frequency modulation of the FM ECDL is shown in a graph. Further results of the model together with experimental measurements characterising the FM ECDL are presented.
