Abstract

A novel fiber-optic thermal source, consisting of a Nd³⁺ doped fiber tip and a pure YAG crystal fiber that grown by LHPG(Laser heated pedestal growth) method, had been studied for laser surgery applications. Pumping by a CuBr laser, the thermal source generated temperature as high as 520 degree(s)C with stability of better than 4% (absolute temperature), the thermal response of the thermal source is about 3 seconds, and the temperature can be controlled by the input laser power. Experimental results show that, the fiber-optic thermal source is promising for laser surgery applications, and is expected to avoid overheating that likely to happen in direct laser tissue interactions.
