Figure 2

(a) Optical setup of the visible laser inactivation system. (b) Photograph of an E. coli bacterial sample irradiated by the second harmonics of a YAG laser in an ultrasonic bath. An E. coli bacterial sample without laser irradiation was also placed in the ultrasonic bath as a control sample to take into account the inactivation caused by ultrasonic vibrations.
