Extended Data Fig. 5

Since photoinjection takes place in the sample plane, while the test pulse is sampled in the detection plane, it is necessary to calibrate the delay between the pump and test pulses. This is done by determining the mapping between the positions of piezo stages that control the pump-test and sampling-test delays, which is accomplished by comparing test waveforms measured in the sample and detection planes.
