摘要：

In order to exploit its potential applications, we experimentally study the dependence of 85Rb-based coherent population trapping (CPT) resonance on N2 buffer gas with 6 vapor cells filled with natural rubidium and N2 . The experiments are carried out at different pressures and temperatures, and the results reveal that higher cell temperature makes the resonance more sensitive to N2 pressure. Thus, it is important to choose a proper buffer gas pressure at a given cell temperature. This work provides valuable data for the application of 85Rb CPT resonance with a buffer gas of N2 .
