Extended Data Figure 3. Power dependence of TR3 spectra of sMMO.

Extended Data Figure 3

16O2 – 18O2 difference spectra obtained using 65 mW (i) and 15 mW (ii) excitation laser power show the same normalized intensity of oxygen vibrations in Q, indicating that no detectable photodecomposition is taking place under current conditions.
