Extended Data Fig. 12: Mechanism of room temperature ODMR.
a, Widefield fluorescence image of E. coli expressing EYFP that was measured in Fig. 5d. The red dot marks the measurement position. b, Readout contrast as a function of time after the onset of the 912 nm readout pulse when it is applied 10 μs after the 488 nm laser pulse ends. A 100 ns microwave pulse is applied 100 ns after the onset of OADF. c, Readout contrast as a function of time after the onset of the 912 nm readout pulse when the microwave drive and readout laser have no temporal overlap. A 100 ns microwave pulse at (2π) × 2.79 GHz is applied immediately after the 488 nm pulse. A 100 ns delay between the microwave pulse and 912 nm readout pulse ensures no temporal overlap.
