Broad and uniform supercontinuum comb generation using an optical pulse synthesizer

在本研究中，利用频域调制合成的光脉冲作为种子脉冲产生宽而均匀的超连续谱。我们改变了脉冲合成的方法，并抑制了脉冲的背景噪声。抑制提高了超连续谱的均匀性。研究了可重构脉冲压缩技术对种子脉冲峰值功率的提高。通过改变初始脉冲波形，控制压缩脉冲波形，实现了亚ps宽的压缩脉冲。

In this study, optical pulses, which were synthesized by frequency domain modulation, were used as seed pulses of broad and uniform supercontinua. We changed a method of the pulse synthesis, and suppressed the background noise of the pulses. The suppression improved the uniformity of supercontinua. We studied reconfigurable pulse compression for peak power enhancement of the seed pulses. The compressed pulse waveforms were controlled by changing the initial pulse waveform, and sub-ps wide compressed pulse was achieved.
