并且进行了实际测量
其结果令人满意。
Abstract
It has been theoretically derived that the far field is also a Gaussian distribution provided that the near field on the output end face of single mode fiber is Gaussian distribution. Based on the obtained theoretical result
a new single mode fiber mode field diameter measuring technique by axially moving the aperture is suggested. Practical measurement shows that the result is quite satisfactory.
