AB  - A free-induction-decay (FID) type optically-pumped rubidium atomic magnetometer 
      driven by a radio-frequency (RF) magnetic field is presented in this paper. 
      Influences of parameters, such as the temperature of rubidium vapor cell, the 
      power of pump beam, and the strength of RF magnetic field and static magnetic 
      field on the amplitude and the full width at half maximum (FWHM) of the FID 
      signal, have been investigated in the time domain and frequency domain. At the 
      same time, the sensitivities of the magnetometer for the single-pass and the 
      triple-pass probe beam cases have been compared by changing the optical path of 
      the interaction between probe beam and atomic ensemble. Compared with the 
      sensitivity of  approximately 21.2 pT/Hz1/2 in the case of the single-pass probe beam, the 
      amplitude of FID signal in the case of the triple-pass probe beam has been 
      significantly enhanced, and the sensitivity has been improved to  approximately 13.4 pT/Hz1/2. 
      The research in this paper provids a reference for the subsequent study of 
      influence of different buffer gas pressure on the FWHM and also a foundation for 
      further improving the sensitivity of FID rubidium atomic magnetometer by 
      employing a polarization-squeezed light as probe beam, to achieve a sensitivity 
      beyond the photo-shot-noise level.
