Mode locking can be induced not only by lossmodulation, but also by phase modulation.
锁模不仅可用损耗调制取得，也可用位相调制来得到。

Taking an external cavity laser diode (ECLD) as an example, calculations indicate that the perturbation analysis may become invalid under lossmodulation.
以可调谐双稳外腔半导体激光器(ECLD)为例，指明了在损耗调制下，扰动近似分析可能会失效。

Considering the fiber loss, an analytic expression of the cross phase modulation induced chirp is derived.
