用于血管成形术的光纤蓝宝石头和金属帽的物理特性

Physical Properties of Sapphire and Metal Fibertips Using for Laser Angioplasty

本文主要叙述了用于血管成形术的光纤金属帽及蓝宝石头的物理持性。比较了两者的温度与激光功率,激光持续时间的关系,并讨论了蓝宝石头输出光斑的特性。

This paper describes the physical properties of sapphire and metal fibertips using forlaser angioplasty including their temperature dependences on laser power and laser duration.Thevariation in output beam spot of sappphire tip is also discussed.
