Detuned-loading effect
WebEfficient preparation of a single atom in a tight microtrap where the collisional blockade mechanism takes effect is a non-trivial subject since the rate of the 2-0 loss channel during loading is large due to the presence of the red-detuned MOT cooling beams and repump beam. These beams are present to provide a reservoir of atoms to load the ... WebSuch devices exhibit detuned-loading effects and the measured values depend strongly on the tuning current of the Bragg section, α-factor behavior is found to agree with earlier …
