摘      要：We experimentally demonstrate a reliable method based on a nanofiber to optimize the number of cold atoms in a magneto–optical trap(MOT) and to monitor the MOT in real *** atomic fluorescence is collected by a nanofiber with subwavelength diameter of about 400 *** MOT parameters are experimentally adjusted in order to match the maximum number of cold atoms provided by the fluorescence collected by the *** maximum number of cold atoms is obtained when the intensities of the cooling and re-pumping beams are about 23.5 mW/cm^2 and 7.1 mW/cm^2,respectively;the detuning of the cooling beam is-13.0 MHz, and the axial magnetic gradient is about 9.7 Gauss/*** observe a maximum photon counting rate of nearly(4.5 ± 0.1)× 10^5 counts/*** nanofiber–atom system can provide a powerful and flexible tool for sensitive atom detection and for monitoring atom–matter *** can be widely used from quantum optics to quantum precision measurement.
