| 摘 要： | 为了对用光纤光栅调谐的光纤激光器相干耦合系统的锁定波长范围进行研究,采用光纤布喇格光栅的反射率分布函数对系统阈值进行比较的方法,得到系统的相干振荡波长应该出现在大约为两个布喇格波长平均值的地方的结果。结果表明,当两个子激光器的可调谐光纤光栅反射的布喇格波长差小到一定程度时,两个子激光器就可以实现相干锁定。

| Abstract: | The locking range in coherently combined fiber lasers was studied by means of the reflection distribution function of the tunable fiber gratings.After comparing the threshold,it was seen that the oscillation wavelength of the coherent radiation occurred near the average of the two Bragg wavelengths.The result shows that the constituent lasers can be coherently combined when the Bragg wavelength difference between the two fiber gratings is small enough. |
