Single mode emission of an external cavity laser was obtained experimentally at 1 GHz modulation with side mode suppression ratio better than 40 dB, 3 dB dynamic line width about 0.1 nm, and 20 dB dynamic line width about 0.3 nm.

• 对所研制的光纤光栅外腔激光器进行了高频调制测量 ；得到了在 1GHz下的单模激光输出 ；边模抑制比在 40dB以上 ；3dB动态线宽为 0 .；1nm左右；2 0dB动态线宽为 0
