Extended Data Fig. 3: Triplet state readout.
a, The EYFP initialized with a 488 nm laser pulse, then the spectra of the collected light recorded during a subsequent 912 nm laser pulse (purple), as well as the fluorescence collected during continuous illumination with the 488 nm laser (green and red). b, After initialization, the time trace of the collected light as a function of time after the onset of the 912-nm laser pulse without (grey), and with (purple) a microwave π-pulse on the Tx−Tz transition. c, The same as b, but on the Ty−Tz transition (blue). Panels b and c are measured at 80K and display similar data as Fig. 1d but over an increased time range.
