Abstract: FIELD: optics. 
     SUBSTANCE: medium is illuminated with laser radiation, spatial-time intensity distribution is registered and phase distribution of incident radiation is determined at the plane being perpendicular to direction of propagation of radiation. The plane has to be plane of incidence of beam onto medium. Spatial-time distribution of radiation intensity passed through medium is registered at plane disposed behind medium on the pass of beam and being optically conjugated with plane of space which plane is perpendicular to direction of radiation propagation and disposed in front of medium. Refractivity non-linearity coefficient is calculated due to comparison of distribution achieved for incident and passed beams. Contribution of all components (nuclear, electronic, striction and thermal) of non-linearity coefficient can be taken into account at relatively low power of incident radiation (up to 1-2GW) for optical media at any state of aggregation of matter without sample destruction. 
     EFFECT: improved precision of measurement.
