摘　　要：以不同波长、不同功率密度激光照射各类细胞，选择最适宜的波长和功率密度具有实验与临床意义。为适应该项研究的需要，设计了会聚透镜与光纤耦合器的距离可以精确调节的耦合系统。它与多种激光器组合，可得到输出功率可调的多种波长的实验条件。使用方便。In biomedical studies on the response of cultured cells in vitro to laser irradiation, it is quite often that different power densities of the laser beam are required in a given experiment. In this paper we report a laser fiber couple system, by which the output power from the fiber tip can be adjusted according to the requirement of the actual investigation. It is carried out by changing the distance between the focusing lens and the coupling tip surface of the optic fiber. The theoretical principle of the system is also discussed.
