XUV intensity and phase for satellite pulses separated from the main pulse by (a) a full cycle and (b) a half cycle of the streaking laser field. The black and red squares represent the actual XUV pulse intensity and phase, whereas the black line and red line represent the retrieved intensity and phase, respectively.
Retrieved satellite pulse contrast for attosecond pulses with full-(black open symbols) and half-cycle separation (red filled symbols) and with (a) linear chirp and (b) flat phase. The satellite pulses with full-cycle separation are always retrieved within an accuracy of 2%, whereas those with half-cycle separation are severely underestimated for large intensity variation.
Interference of satellite pulses in the photoelectron energy spectrum for streaking with intensities of (black solid line) and (red dashed line). (a) Full-cycle separation, delay . (b) Full-cycle separation, delay . (c) Half-cycle separation, delay . (d) Half-cycle separation, delay .
Retrieved satellite pulse contrast for attosecond pulses with full-(black open symbols) and half-cycle (red filled symbols) separation and with (a) linear chirp and (b) flat phase. The satellite pulse contrast is always retrieved within 4% for full-cycle separation. For half-cycle separation, the contrast can be underestimated by more than an order of magnitude. The effect is more severe for contrast of 0.01 than a contrast of 0.1.
