| Abstract: | Stabilization of a passive harmonically mode-locked laser is demonstrated by directly modulating a 980-nm pump diode laser
used both to provide gain and to optically modulate an intracavity saturable absorber. The results indicate a reduction of
the undesired laser modes by more than 55 dB. The timing jitter was decreased by 9 dB.
