Fast and high probability production of single atoms in a cesium (Cs) magneto-optical trap (MOT) is demonstrated by using light-induced atomic desorption(LIAD). The atom’s loading time in a high-gradient vaporcell MOT is reduced by using the violet light emitting diode (LED), which can fire atomic desorption from the inner wall of vacuum glass cell to increase the density of background Cs atoms. The influence of the intensity of the violet LED light to the background atom number is also discussed. Finally, the measured occupation probability of one atom, two atoms, and three atoms are 98.2%, 95.0%, and 80.1% respectively in the MOT. Moreover, this technique could be especially useful for the deterministic loading of a single atom in a single microscopic optical tweezer or in two-dimensional array of microscopic optical tweezer.
