| 摘 要： | The absorptive properties of the atomic transition in the Rb^85 D2 (A) line (5S1/2-5P3/2) at 780.Onm are measured by using a continuous tunable diode laser and a CCD detector in Rb vapour cell under the condition of extremely weak incident intensity. When the intensity of incident light decreases from 420pW/cm^2 to 0.03pW/cm^2, the transmittance is found to be independent of the incident intensity within our experimental accuracy.
