Abstract

Coherent radiation at the wavelength of stimulated Brillouin scattering concurrent with the incident laser beam has been observed for the first time in the aqueous suspension of dielectric nanospheres with an average diameter of about 290 nm at their concentration ranging from about 10⁹ to 10¹¹ cm−³. The theory of the phenomenon is constructed.
