Tissue Response to Lasers The light energy from a laser beam can have differ- ent interactions with the target tissue depending on two principal factors: 1. Wavelength of the laser used 2. Optical properties of the target tissue These two variables determine the following responses (Fig. 19.6): ● Reflection . The laser beam reflecting or redi- recting itself away from the tissue surface and having no effect on the target tissue.
