Figure 1

$g_{D_1,D_2}^{(2)}(\tau )$ versus delay $\tau$ for the fluorescent light from a beam of atoms with average number $\overline{N}=0.1$. The line at $g_{D_1,D_2}^{(2)}(\tau )=1$ represents the Poisson limit for coherent light of the same mean counting rates at $(D_1,D_2)$. $\tau$ is measured in units of the transit time $t_0$. The generalized Rabi frequency ${\Omega }^{\prime }{t}_0=25$, and transverse decay rate $\beta t_0=0.1$. The lower trace is for background to signal ratio $=0.5$ (appropriate to Ref. 1), while the upper trace has no background [3].
