Abstract

We demonstrate wide-band ultrafast optical pulse generation at 1, 1.5, and 2 μm using a single-polymer composite saturable absorber based on double-wall carbon nanotubes (DWNTs). The freestanding optical quality polymer composite is prepared from nanotubes dispersed in water with poly(vinyl alcohol) as the host matrix. The composite is then integrated into ytterbium-, erbium-, and thulium-doped fiber laser cavities. Using this single DWNT-polymer composite, we achieve 4.85 ps, 532 fs, and 1.6 ps mode-locked pulses at 1066, 1559, and 1883 nm, respectively, highlighting the potential of DWNTs for wide-band ultrafast photonics.

摘要

我们展示了使用基于双壁碳纳米管（DWNTs）的单一聚合物复合可饱和吸收体在1μm、1.5μm和2μm波长处产生宽带超快光脉冲。这种独立的光学质量聚合物复合材料由分散在水中的纳米管与聚乙烯醇作为主体基质制备而成。然后将该复合材料集成到掺镱、掺铒和掺铥光纤激光腔中。利用这种单一的DWNT-聚合物复合材料，我们分别在1066nm、1559nm和1883nm波长处实现了4.85ps、532fs和1.6ps的锁模脉冲，突出了DWNTs在宽带超快光子学方面的潜力。
