"Table 5" of "Positronium laser cooling via the $1^3S$-$2^3P$ transition with a broadband laser pulse"

Number of Ps atoms with v$_{1D}$ < 3.7 × 10$^4$ m/s, as a function of the cooling laser frequency detuning, normalized to the number of Ps atoms in the absence of all lasers. The dashed horizontal line represents the reference population of Ps in this velocity range with the cooling laser off. The highest observed relative increase is 58(9)% at a cooling laser frequency detuning of −350 GHz. The semitransparent bands represent the statistical uncertainties (one standard deviation of the average).
