英语翻译
Stretching axial FBG can adjust the lasing wavelength
.Upon 980 nm pumping,the experiment shows that the lasing generation at 1550
nm determined by the FBG can be observed,maximum arriving to 6.3-dBm output
with multimode.Further,the laser is verified by observing the exciting threshold
and removing the FBG in the resonator.The single mode can be selected out by twining the multimode fiber round a cylinder.

Answer 1

自己翻的,这个领域是小白,若有错误请见谅通过轴向拉伸FBG可以调整激光的波长.在980nm的激励（泵动）下 ,实验显示可以通过FBG来观测到生成1550nm激光,多模式下最大达到6.3-dBm的输出.另外,通过活跃（兴奋）门限值和去...
