Abstract

We have demonstrated a high order harmonic mode-locked erbium-doped fiber laser by utilizing 2H-MoTe2 film as a saturable absorber (SA). The SA is synthesized by depositing 2H-MoTe2 film on a D-shaped fiber. The nonlinear optical properties of the 2H-MoTe2 SA are characterized, showing a modulation depth of 14.7% and a saturation intensity of 3 GW cm−2. Through optimizing the pump power and intra-cavity polarization state, a 171st-order harmonic soliton at 0.9 GHz repetition frequency with a pulse width of 1.06 ps was obtained. The fundamentally mode-locked pulse train had a pulse width of 1.03 ps and a repetition rate of 5.33 MHz. To the best of our knowledge, the 171st-order harmonic soliton is the highest operating repetition frequency that has ever been demonstrated in a 2H-MoTe2 SA mode locked fiber laser. The results indicate the potential of 2H-MoTe2 SA at high repetition rates regimes, which could benefit for future possible application.

基于 2H-MoTe2 可饱和吸收体的 171 次谐波孤子掺铒光纤激光器

我们利用 2H-MoTe2 薄膜作为可饱和吸收体（SA），演示了一种高阶谐波模式锁定的掺铒光纤激光器。这种可饱和吸收体是通过在 D 型光纤上沉积 2H-MoTe2 薄膜合成的。2H-MoTe2 SA 的非线性光学特性显示，调制深度为 14.7%，饱和强度为 3 GW cm-2。通过优化泵浦功率和腔内偏振态，获得了重复频率为 0.9 GHz、脉冲宽度为 1.06 ps 的 171 阶谐波孤子。基本锁模脉冲序列的脉冲宽度为 1.03 ps，重复频率为 5.33 MHz。据我们所知，171 次谐波孤子是迄今为止在 2H-MoTe2 SA 锁模光纤激光器中演示的最高工作重复频率。这些结果表明了 2H-MoTe2 SA 在高重复频率下的潜力，这对未来可能的应用大有裨益。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
