Additionally, it has to be noted that the nanosecond long pulses contain fast temporal oscillations (≥ 1.7 GHz) which might not be visible when using a “slow” detection method. An example for three different [...] Central wavelength 1030 nm 515 nm Pulse duration (FWHM) 3.5 ps, 275 ps or 0.4 ns – 10 ns ≈ Original/1.41 Signal to PHELIX emission ratio Not measured > 110 Temporal pulse shape Gaussian like < 0.4 ns & [...] ≤ 7 mJ ≤ 2 mJ Energy stability over 45 minutes < 5 % RMS < 5 % RMS Timing jitter to PHELIX pulse < 1.95 ps Possible delay to PHELIX pulse ± 2.4 ns (shiftable up to ± 200 ns, requiring setup changes) Repetition
