Abstract

This work represents an experimental study to measure the spectrum of transmission and attenuation coefficient of water samples taken from different places in Iraq. Nd:YAG laser source doubled frequency was used as transmitter, the laser pulse was directed through the cells experimental of different length, which developed in laboratory, were measured the transmission and attenuation coefficients in many kind of Iraqi’s waters, that was middle of Tigris, and middle of Euphrates. We have found that the ratio between absorption and scattering was three times in Iraqi’s waters.
