narrow linewidth laser meaning in Chinese

窄线宽激光器

In the yb3 + - doped single or double clad fiber lasers by using few - mode fiber bragg gratings as wavelength reflectors , the linewidth of the output laser is smaller than 0 . 1nm , which shows that such a scheme can produce narrow linewidth laser
最吸引我们的是使用这种光纤光栅做为腔镜组成的掺yb3 +单包层和双包层光纤激光器有着小于0 . 1nm的3db带宽,说明少量模光纤布拉格光栅具有较窄的反射峰。
