摘要:

相位噪声对超快脉冲在通信、超快诊断、材料科学、生物学等领域的应用具有重要意义。本文研究了两种碳纳米材料,单壁碳纳米管和氧化石墨烯,用于超快光子学中的噪声抑制。墙纸SA的各种性质,如饱和强度,光吸收和纯度,被发现是决定超快脉冲的相位噪声的关键因素。通过优化碳材料自组装结构的上述参数,实现了飞秒光纤激光器的低噪声输出。实验表明,在10kHz处,相位噪声的抑制率可达10dB以上。据我们所知,这是第一次,不同的碳材料为基础的SA和锁模激光器的相位噪声之间的关系进行了研究。这为在被动锁模光纤激光器中获得高质量的超短脉冲奠定了基础。

英文摘要:

Phase noise is very important for the ultrafast pulse application in telecommunication, ultrafast diagnose, material science, and biology. In this paper, two types of carbon nano-materials, single-wall carbon nanotube and graphene oxide, are investigated for noise suppression in ultrafast photonics. Various properties of the wall-paper SAs, such as saturable intensity, optical absorption and degree of purity, are found to be key factors determining the phase noise of the ultrafast pulses. A reduced-noise femtosecond fiber laser is experimentally demonstrated by optimizing the above parameters of carbon material based SAs. The phase noise reduction more than 10 dB at 10 kHz can be obtained in the experiments. To our knowledge, this is the first time that the relationship between different carbon material based SAs and the phase noise of mode-locked lasers has been investigated. This work will pave the way to get a high-quality ultrashort pulse in passively mode-locked fiber lasers.
