Hello Carsten, I’m not sure I can answer all of these questions. It must be possible to convert the energy delivered for each spot into a number of photons per spot according to the frequency of these. For the rest, the principles that govern the creation of femtosecond wave trains ensure their sequential emission, as « pulses ».

Thanks for this enlightening summary that puts numbers into perspective. What I’m curious about is how many beams need to be in focus to deliver the energy for a spot? What is the angle between the beams?
How close the beams need to come at the same time point to create what is generally termed « in focus »?
If you know an article about these questions I’m happy to read it.
Best,
Carsten
