Abstract We have observed spontaneous parametric four-photon scattering in electrolytic solutions (alkali halides and alkaline earth halides in water). The spectral, temporal, and spatial intensity distributions of the scattered light have been measured. Using a Q-switched ruby laser as a pump, and a CuSO4-solution as a filter we observed signal wavelengths in the range from 350–550 nm with a maximum intensity at 480 nm for all of the investigated solutions. This radiation is emitted into a cone with a half-angle of roughly 60 mrad. In comparison to pure water the scattered radiation in electrolytes has a much higher intensity. Most of the experimental results confirm predictions of the theory of spontaneous four-photon scattering.
