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.
