The operation of a self-starting, passively harmonic modelocked, figure-eight laser is experimentally demonstrated. A stable pulse train with near half duty-cycle is produced at a repetition rate of 1.7 GHz at 1536 nm wavelength without any starting/triggering mechanism and stays modelocked as long as it is being pumped.
