Canard cascading in lasers with slow-fast coupling

In this presentation I consider a fast-slow system of mean-field coupled semiconductor lasers. The canard cascading is a complex regime that alternates between canards and relaxation oscillations. Using geometric singular perturbation theory, we perform the fast-slow analysis of the system and explain the formation of canards. The heterogeneity of the lasers is identified as the key cause for the occurrence of the phenomenon.
