Ten years ago it was reported that external optical feedback as weak as 1% can induce a semiconductor laser to suddenly lose its coherence: its linewidth changes from typically 100 MHz to more than 20 GHz. This phenomenon has been called Coherence Collapse and attracted a lot of research effort. By now most of the deterministic properties of Coherence Collapse are identified. In the routes to chaos the interplay between the relaxation oscillations and the delay-induced resonances of the external cavity is considered to be the key physical phenomenon.1
