Figure 5. The distributions of traveling time (${t}_{{\rm{R}}}-{t}_{{\rm{SI}}}$) for (a) $\phi =0,$ (b) $3\pi /16,$ (c) $7\pi /16$ and (d) $\pi /2.$ The CRTC laser wavelength is 800 nm and 400 nm, and the laser intensities $2\times {10}^{14}\,{\rm{W}}\,{{\rm{cm}}}^{-2}.$ The numbers with arrows indicate the main distribution of travel time. |
