摘要
利用振幅调制连续波(CW)抽运,数值模拟了在噪声背景下不发生时域混叠的短脉冲序列和梳状频谱的产生。研究结果表明,振幅调制可以很好地改善短脉冲序列时域稳定性和梳状频谱稳定性,调制参量对输出信噪比和梳状频谱的稳定性起到关键作用;并得到了梳状频谱稳定性好的调制参量区域。
Based on the background noise, the generation of short pulse series and comb-like spectrum are numerically simulated by the amplitude modulation of continuous wave （CW）. The results show that the stability of short pulse series and comb-like spectrum can be improved by the amplitude modulation. The modulation parameters play a key role on the output signal-to-noise ratio（SNR） and the stability of comb-like spectrum. The region of modulation parameters with stable comb-like spectrum is also obtained.
