On the basis of a FDTD-technique to the solution of the Maxwell equations the numerical modeling of two-dimensional spatial field distribution of multi-photon excited fluorescence in the vicinity of a micron spherical ethanol droplet upon illumination by laser beam was carried out. It is considered that fluorescence sources are located in "hot spots" in a spherical particle and can have various capacity and volume. It is established that the field of fluorescence radiated from back and forward hemispheres of a particle (in relation to a direction of exciting radiation), is characterized by a various orientation. With the increase of multi-photon order of the excitation of fluorescence from ethanol droplet and corresponding increase in a disbalance between sources capacity, the fluorescence is emitted primarily in the "forward" direction; the effective angular divergence of fluorescence in the "backward" direction changes insignificantly.
