Abstract :
A saturable-absorber-free vertical-external-cavity surface-emitting laser is presented which is harmonically modelocked. Modelocking is initiated via fine-tuning of an aperture which is placed near one of the cavity´s end mirrors. Fundamental modelocking is observed along with the second and third harmonic operations for increased optical pump powers. The system features pulse durations penetrating the femtosecond regime at a wavelength of 1014 nm.
