Fig. shows the corresponding fitted forward rate constants from the dynamics in Fig. (red) and Fig. unaffected for Q ≥ 500 (Γ ≤ 6 meV) and begin to decrease as Q decreases below 500. This transition point between affected and unaffected rates along Q corresponds to the regime where hΓ ≈ V l because for hΓ ≪ V l , the laser pumping can rapidly replenish any UP population lost through cavity loss while for hΓ ≫ V l , the UP population is lost faster than the laser pumping can replenish it.
