(a)–(c) show different profiles of the laser pulse for , , , respectively, (d)–(f) and (g)–(i) show the corresponding wake scalar potentials and electric fields. The red, black, and green colorsdenote the fast rise, the symmetric, and the slow rise cases, respectively.
Wakefield distributions of (a) , (b) , (c) at the same time in the case of . A p-polarized laser pulse of wavelength , a peak amplitude , and a plasma density of are used.
Distributions of (a) minimum and maximum wakefield potentials ( and ) and (b) integral versus the chirp parameter .
The maximum wakefield potential amplitude versus the laser pulse length when an un-chirped laser pulse has asymmetric envelope.
Distributions of laser electric field and wake scalar potential, generated by the laser pulse with different chirp from the analytical results.
Wakefield distributions in the case of (black line), (red line), (green line), (blue line), (cyan line) from (a) analytical and (b) simulation results at . A p-polarized laser pulse of wavelength , a peak amplitude , and the plasma density of are used.
(a)–(c) show the laser pulses in the case of , , , respectively at and (d)–(f) show the corresponding wakefields. The other parameters are the same as in Fig. 6(b).
