In an electromagnetic field consisting of two waves omega and omega - propagating in opposite directions, and having frequencies omega 12 delta omega and omega - 12 delta omega, respectively, polarizable particles are dragged along in the direction of the omega wave. The stimulated scattering of omega photons into omega - photons supplies the medium with the energy to be dissipated against viscous forces. Conversely, if the p particles are forced into motion in a strictly stationary field, the ratio of the respective intensities of omega and omega - will change. It is shown that these two-photons drag effects, which are closely tied to fluctuation in scattering concentration, can be used to measure the number, size and mobility of charged or neutral particles dispersed in a host medium.
