对增益开关分布反馈半导体激光器（ＧＳ－ＤＦＢ－ＬＤ）加法布里－珀罗共振腔滤波方法产生变换限制脉冲源进行了理论分析，设计出将不同光源变为变换限制脉冲所需的滤波器带宽，并计算出相应的输出脉冲脉宽谱宽，从实验上获得了变换限制脉冲，本文还研究了测谱仪器分辨率对测量结果的影响，导出了一套测量修正理论。
The reason why the pulse width of the filter is limited by changing the pulse width of the pulse source with different light sources into a transform limited pulse is proposed. , And calculate the pulse width of the corresponding output pulse width, obtained from the experiment transform limit pulse, this paper also studied the resolution of the spectrometer instrument on the measurement results, derived a set of measurement and correction theory.
