Questions:
Multiple pumps per probe/probes per pump?
Relative size of pulse vs. delay? pulse much less than delay
As well as observing a reaction, there is the possibility of active control by using short pulses to affect the outcome of a chemical reaction.
Frequency control - Brumer-Shapiro
The interference between two degenerate pathways. Analogous to affecting the interference in Young's slits experiments.

Shaping the light pulse allows clever control of the optical pulse to give greater control of the chemical reaction. - Question: how does this depend on variations in the input light pulse? e.g. a varying electron bunch will produce a varying photon pulse, which will change the resulting shaped pulse. This must be some sort of limitation.
26th April:
There is a limit to the repetition rate that can be used on the VUV-FEL which arises from the limit rate of time-of-flight detectors. This places a limit of around 10s of kHz for certain types of experiment.
