针对难以从信号光获取偏置工作点信息的应用场景，分析了不同波长激光通过强度调恪器的输出表现，提出一种引入参考光的重频光脉冲整形方案。方案通过波分复用器引入并分离参考光，利用不同波长激光 经强度调恪器后输出光的关联性和参考光的强度信息间接获得信号光的偏置工作点信息。实验结果表明．该方案可以有效获得偏置工作点信息，不受信号光变化的影口。

Facing the application scene which is hard to obtain the offset working point information from signal light, a kind of repetition-frequency optical shaping scheme with reference light is proposed after analyzing the output performance of different wavelengths of signal light passing through the intensity modulator. The wavelength division multiplexer is used to import and separate the reference light. Benefited from the relevance of output laser of different wavelengths passing through the intensity modulator, it is possible to obtain the offset working point information of signal light based on the intensity of reference wave. It is possible to obtain the offset working point information effectively in the scheme and is not effected by signal light change.
