WebbEssentially, while the finesse relates the resonance bandwidth to the free spectral range, the Q factor relates it to the average optical frequency. If one increases the resonator's round-trip length while keeping the power losses per round trip constant, the finesse will stay constant, while the Q factor will increase.
