The spin fluctuation in rubidium atom gas is studied via all-optical spin noise spectroscopy(SNS).Experimental results show that the integrated SNS signal and its full width at half maximum(FWHM) strongly depend on the frequency detuning of the probe light under resonant and non-resonant conditions.The total integrated SNS signal can be well fitted with a single squared Faraday rotation spectrum and the FWHM dependence may be related to the absorption profile of the sample.
