(a) Autocorrelation measurement of the MPC output pulses. The insets show the measured and retrieved FROG traces. (b) Retrieved temporal profile and phase as well as retrieved fundamental spectrum and spectral phase at 1030 nm (inset). The spectral resolution is too low here to fully resolve the SPM ripples of the spectrum at the output of the MPC, limited by the resolution of the FROG unit (Femtoeasy FROG). The integration time for the measurement was 100 µs in the central part of the burst. |
