We present a sesam-free harmonically mode-locked vertical-external-cavity surface-emitting laser. Mode-locking is initiated by introducing a slit near to the high reflective end mirror of our Z-shaped laser cavity. Beside single pulse operation we observed second as well as third harmonic mode-locking for higher pump powers. Our system features pulse durations penetrating the femtosecond regime at a wavelength of 1014 nm.
