The results show that injection locking synchronization is realized when injection rate is large enough. In the injection locking regime, similarity index is larger for external modulation than that for direct modulation. If injection rate keeps unchanged, synchronization is little affected by modulation index, but it is affected by modulation frequency. Since outputs of the master laser are antiphase for direct modulation and external modulation, the fluctuations of similarity index with modulation frequency for the two lasers are contrary.

研究结果表明：当注入强度足够大时，系统实现注入锁定同步，外部调制的相似指数大于内部调制；注入强度恒定时，同步品质几乎不受调制指数的影响，而受调制频率的影响；由于内部、外部调制引起主激光器的输出反相，两种调制方式下同步品质随调制频率的变化趋势也相反。

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.
