Bright High-Harmonic Generation through Coherent Synchrotron Emission Based on the Polarization Gating Scheme

Figure 3

(a, b) Harmonics generation efficiency as a function of both plasma scale length and delay of the two circular polarized pulses in polarization gating. (c, d) The number and corresponding peak intensity of gated attosecond pulses (30th–100th) as a function of preplasma scale length and delay between the two circular polarized pulses in the polarization gating scheme. The intensity of the incident field is a = 10, the pulse duration τ is 16 fs, and solid-target density is 100 n_c. Results for harmonics within the range from 10th to 20th (a) and from 20th to 100th (b) are presented.
