Figure 2

Waveforms of the TL pulse, measured for three cavity delays. The delay difference between the first (blue curve) and the last measurement (green curve) was about 2.2 ps. (a) A Zoom-in view around a phase pulse, where the pulse is obtained between about \(-0.1\) ns to 0.3 ns. (b) A zoom-in view on a cycle in the CW part of the waveform, which is highlighted by a blue box in Fig.2(a). (c) A zoom-in view on part of the phase pulse, which is denoted by a pink box in Fig.2(a), with a closer zoom-in view around the time when the minimum amplitude is obtained in the temporal-locked (TL) part of the pulse. The change in the delay causes a large phase shift of the CW part of the waveform, while the extrema points in the TL part of the pulse almost do not change their timing. The measurements were performed by a real-time oscilloscope with a sampling rate of 80 GS/sec.
