the evanescent field

基本解释

We present a method to measure the evanescent field by Michelson interferometer.
提出了一种用迈克尔逊干涉仪探测隐失场的方法。
It utilizes the evanescent field confined at the tiny aperture for providing images of object surfaces with a resolution beyond the classical optical diffraction limit.
这种显微镜利用局限在微小孔径上的隐失场提供物体表面形貌的细节，其分辨率可突破传统光学的衍射极限。
Pumped by evanescent wave along the fiber axis, dye gain is confined in the evanescent field of whispering gallery mode (WGM) of the fiber, which leads to a low pumping threshold for lasing emission.
采用轴向隐失波激励增益的方式，使激光增益区域局限在光纤回音壁模式的模场区域内，显著地降低了回音壁模式光纤激光辐射的抽运阈值，由此形成一种低阈值的回音壁模式光纤激光器。
