The bactericidal effect of Argon ion laser (CW, 5W, The coherent, INNOVA 400-10 series ion laser) on 3 aerobic bacteria : Staphylococcus aureus, Entrococcus faecalis and Pseudomonas aeruginosa was investigated. 106 CFU/ml of each of these bacteria were exposed to laser radiation for various time intervals and checked microbiologically to determine lethal energy does (LED). This energy was then exposed in intervals, summation of which was equal to LED. It was found that the LED for S.aureus was 3.6 KJ/cm2, E.faecalis 3.8 kJ/cm2, and Ps. aeruginosa 6.6 KJ/cm2. There was specific lethal threshold energy density and it must be delivered in one shot.
