"Table 4" of "Positronium laser cooling via the $1^3S$-$2^3P$ transition with a broadband laser pulse"

One-dimensional transverse Doppler profiles of the Ps cloud with and without interaction with the 243 nm cooling laser beam at a fixed frequency detuning of −200 GHz. The semitransparent bands represent the statistical measurement error (one standard deviation of the average).

在固定频率失谐为-200 GHz的条件下，有无与243 nm冷却激光束相互作用的正电子素云（Ps）的一维横向多普勒轮廓。半透明色带代表统计测量误差（平均值的一个标准差）。
