| Abstract | ||
| In this study was used diode lasers to kill Escherichia coli.Two types of diode laser have been used. The first one 3-watt 810 nm wavelength and the second 7 watt wavelength 1064 nm. Irradiation of samples was taken place from the physiological saline containing the Escherichia coli in three sizes 0.3,0.2, 0.1 cm ³ in test tubes of size 0.5 cm³. Samples were irradiated at different periods of time for each laser. The results showed that after each irradiation a highest kill of 100% of the bacteria occurred by used laser diode (3 W) through a period of 20 minutes. In the diode laser (7 W) a recording of the highest kill rate of 100% has been obtained in 1.5 min period. | ||
