Paper Abstract

During the laser treatments in biomedical fields the patient must not run any risk due to a damage of the fiber delivery systems. Such damages are usually monitored by backscattering. Here an investigation of backscattered signals due to flat, bulb and damaged fiber tips is reported. A fiber directional coupler was employed which has shown noticeable advantages with respect to the conventional beam splitter technique (BST). These results have been exploited to design a practical monitoring device which has been inserted int a fiber-optic delivery system, fed by a Nd:YAG laser.
