Laser Sintonizável em Regime Mode-Locking Harmônico (HML) em Cavidade em Figura-de-Oito

This paper of Scientific Initiation describes the assembly and testing of a mode-locked laser operating on passive mode in a figure-of-eight cavity. The laser is composed by a single-mode fiber optic ring containing an SOA as medium of gain. Mode-Locking was obtained with MHz repetition rate of the fundamental and harmonic frequencies (Harmonic Mode-Locking).
