1. Method for generating short optical pulses comprising the steps of:
operating a single section semiconductor laser in a nonlinear regime to emit chirped optical pulses at an output facet of the laser cavity, and compressing the chirped optical pulses outside the laser cavity using a dispersive element in order to generate the short optical pulses; wherein the single section semiconductor laser is operated with a DC injection current; and wherein the injected DC current is such that the generated optical intensity within the laser causes nonlinear effects inside the gain medium of the laser's cavity.
