Jing Wang, Jingui Ma, Peng Yuan, Daolong Tang, Binjie Zhou, Guoqiang Xie, Liejia Qian

AI总结:

本研究实验探究了光参量啁啾脉冲放大中由信号散射引发的新型参量噪声的特性,发现其空间域表现类似参量超荧光但强度更高、时域可继承信号啁啾并压缩,且对脉冲对比度影响小但会显著降低转换效率。

摘要:

我们通过实验研究了一种新型参量噪声,该噪声由信号散射引发,并经光参量放大得到增强。这类散射噪声在空间域的表现与参量超荧光类似,但强度通常高得多。在时域中,它继承了信号脉冲的啁啾,可被良好压缩。我们证实,这种散射引发的参量噪声对放大后脉冲的对比度影响很小,但会大幅降低转换效率。

英文摘要:

We experimentally study a new kind of parametric noise that is initiated from signal scattering and enhanced through optical parametric amplification. Such scattering noise behaves similarly to the parametric super-fluorescence in the spatial domain, yet is typically much stronger. In the time domain, it inherits the chirp of signal pulses and can be well compressed. We demonstrate that this scattering-initiated parametric noise has little influence on the amplified pulse contrast but can degrade the conversion efficiency substantially.
