摘要：

The temperature of the remaining trapped Rb-87 atoms gradually decreases as the intensity of the ionizing lasers increases. And the relationship between the temperture and atom number of the remaining Rb-87 atoms follows an exponential law. This is mainly due to that the photolonized atoms in the state of 5 P-2(3/2) have higher velocity caused by the detuning of cooling laser, and they escape from the trap after becoming ions. In addition, ion-atom interaction may play a role at a higher ion density.
