Figure 1
Laser and X-ray pulses in the time and frequency domains. (a) X-ray synchrotron pulses with period T and laser pulses with the identical period delayed by a time Δt impinge on the same detector. (b) Time profile of the detector output, showing the sum of the two pulse trains. (c) RF spectrum analyzer output from the detector signal, showing the harmonics of the fundamental frequency. These peak intensities are a function of the time delay Δt. |
