Abstract

We present a new technique for laser radiation delivery into a precise (micron-and submicron-scale) tissue area using a smart, tissue-activated optical fiber probe. The operating principal of the laser delivery system is based on the use of a delivery fiber with a specially angle-shaped tip. When the fiber tip is out of the tissue area, the laser emission is backreflected at the angled tip due to total-internal-reflection. However, when the fiber tip is placed on absorbing tissue, it becomes “transparent” for laser emission because of the frustrated-total-internal-reflectance and the energy then is coupled into the absorber.
