We have investigated the spin preparation efficiency by optical pumping of single Mn atoms embedded in CdTe/ZnTe quantum dots. Monitoring the time dependence of the intensity of the resonant fluorescence during the optical pumping process allows direct probing of the efficiency of the Mn spin initialization, providing preparation and read‐out in the same step. The efficiency measured can reach 75% at zero magnetic field and occurs in the tens of nanosecond range when a laser resonantly drives at saturation one of the quantum dot transition.
