Abstract

Spectroscopic method of dangerous substances and microorganisms detection in water is developed. The method is based on analysis of the secondary emission spectra (Raman scattering and fluorescence spectra) of water samples. These spectra were recorded with time delay with respect to exciting light pulse. The excitation was produced by the pulsed ultraviolet radiation from copper vapor laser with non-linear optical crystal cell.
