A new set of nonlinear rate equations that can describe the external cavity semiconductor laser with two optical feedbacks is proposed. The dynamics of the semiconductor laser with two optical feedbacks are studied. It is found that when lasers are biased above the threshold and operate in regime V, another feedback can induce low frequency fluctuations.
