Fig. 3. ACF curves evolution (left column) of the intensity time series in the RTUC-SLs when γ∈[15,150] ns−1. The ACF (middle column) and PE (right column) curves of each laser for γ=15, 30, and 80 ns−1 (from top to bottom for each laser) are presented for comparison.

Fig. 4. The evolution of the ACF curves (left column) of the phase time series in a RTUC-SLs when γ∈[15,150] ns−1. The ACF (middle column) and PE (right column) curves of each laser for γ=15, 30, and 80 ns−1 (from top to bottom for each laser) are presented for comparison.

Fig. 5. The ACF peak versus γ, where the results for the intensity (|E(t)|2), phase (ϕ(t)=Arg[E(t)]), real (Re[E(t)]), and imaginary (Im[E(t)]) parts of the complex field are contained. (a) corresponds to SL1, (b) corresponds to SL2, and (c) corresponds to SL3.
