Abstract
In this paper , nitrogen laser system with wavelength 0 .337μm was used to kill the Escherichia coli bacteria at pulse duration 150 μJ . samples of physiological solution containing Escherichia coli bacteria with three sizes of (0.2,0.2,0.3) cm3 was irradiated in test tubes with size 0.5 cm3 at different periods time . After wish 30 minute irradiation the results showed highest percentage bacteria killing which reached to 100%and that lead to perfect purification for water .
