| 摘 要： | 设计了一种将半导体光放大器耦
合于光纤激光器腔内的结构，以抑制光纤激光器的相对强
度噪声。基于半导体光放大器的增益饱和效应，将光纤
激光器在弛豫振荡峰处的相对强度噪声抑制了30 dB。更进
一步地，通过腔内的放大器结构使得放大器内部的光学
强度达到一个稳定态，最终使得激光器的频率噪声没有因
光放大器的加入而产生劣化。

| Abstract: | To suppress the relative intensity
noise (RIN) of fiber DFB lasers, a structure which couples
a semiconductor optical amplifier (SOA) into a fiber laser
cavity is designed. On the basis of the gain saturation
effect of the SOA, 30 dB RIN of the fiber laser at the relaxation
oscillation frequency is suppressed. Furthermore, the optical
intensity inside the SOA reaches a balanced state via the
intracavity SOA structure. Finally, the frequency noise of the
laser does not degrade with the addition of the SOA. |
