纳米级光纤探针的拉制与镀膜

The Method of Pulling and Plating Film Nanometric Optical Fiber Probe

光学显微镜希望能够得到更高的分辨率 ,作为高分辨率探测系统中的关键部分——纳米级光纤探针的研制则显得尤为重要 .介绍一种利用激光器加热 ,通过重物在光纤一端拉制并进行镀膜的方法 .采用该方法可得到尖端曲率半径小于 4 0

The key part of the high resolution detector system, being the nanometric optical fiber probe, is the most important. A specific procedure of fabrication optical fiber probe and gold plating are presented. The high power laser heating the optical fiber and pulling it by gravity is used in this method. The tip of less than 42nm curvature radius is obtained.
