Spectrum of the amplitude-modulatedwave is observed by a radio frequency spectrum analyzer and amplitude values of every spectrum are recorded at the upper sideband or lower sideband.
In this paper the model of two level atomic momentum spread in amplitudemodulated standing light wave was investigated.

The amplitudemodulatedwave with any modulation factor is discussed in this paper. Its expression, spectrum and formula of the modulation factor, modulation efficiency, SNR gain are given.
