一种用于在光纤表面产生高温的新技术被开发用于使用输出功率低于10 W的低功率半导体激光器的医疗应用。使用功率水平为4-6 W、脉冲持续时间为180 ms、波长为980 nm的半导体激光器，对激光耦合光纤尖端进行一次处理，使其在距离尖端表面100 µm的深度处含有一定量的Ti，从而可以有效地吸收激光能量并将其转化为热能。随着连续的激光脉冲照射，尖端加工的纤维（TP纤维）作为一个可重复的精细热源，其温度被测量为超过3100 K的基础上双色测温。陶瓷和铌板的加工，这是很难烧蚀直接低功率（6 W）照射，成功地证明了通过接触TP纤维激发相同的功率。
A new technique for generating high temperatures on the surface of an optical fiber is developed for medical applications using lower-power semiconductor lasers with output powers lower than 10 W. Using a power level of 4–6 W semiconductor laser with a pulse duration of 180 ms at a wavelength of 980 nm, a laser-coupled fiber tip was once processed to contain a certain amount of Ti with a depth of 100 µm from the tip surface so that the laser energy could be efficiently absorbed to be transferred to thermal energy. With consecutive laser pulse irradiation, the tip processed fiber (TP fiber) served as a reproducible fine heat source whose temperature was measured to be in excess 3100 K based on two-color thermometry. Processing of ceramic and niobium plate, which are hardly ablated with direct low power (6 W) irradiation, was successfully demonstrated by contacting the TP fiber excited with the same power.
