Optical Comb Frequencies Stabilization And Super Mode Noise Suppression Of Harmonically Mode Locked Semiconductor Ring Laser Using A Single Etalon

Using an intracavity Pound-Drever-Hall technique, simultaneous optical frequency comb stabilization within ±3 MHz range and supermode phase noise suppression were demonstrated for a 10 GHz harmonically modelocked semiconductor ring laser resulting in timing jitter of 63.5 fs integrated from 10 Hz to 10 MHz
