• I have my large slot (81640A/680A/642A/682A) tunable laser connected to an OSA. Why don‘t I see any change in the measured spectrum of the laser when coherence control is activated?

    Coherence control increases the linewidth of the laser from 100KHz to 500MHz(typical). At 1550nm this relates to a wavelength change of .004nm. The wavelength resolution of the OSA is .06nm resolution bandwidth minimum. It cannot resolve a .004nm change.
