Abstract

Spatial, temporal, and spectral characteristics of stimulated scatterings (SS) of light, excited in water, have been investigated both in nano- and picosecond range in different experimental conditions and compared with the analogous properties in other liquids. The results can give important information about the structure of water, its purity, and additions, which may lead to its pollution. Conditions have been defined for stimulated excitation of SS in one spatial mode and with maximum pulse conversion. Stimulated scatterings of light can be used for water quality control, which may be fulfilled in a very short time, and for information processing: amplitude-phase structure of complex light fields may be registered in water as dynamic hologram and reconstructed in a real-time scale.
