We report a novel graphene oxide derived nanomaterial, carboxyl graphene oxide (GO-COOH) based saturable absorber (SA) for ultra-short pulse generation. Our GO-COOH based SA demonstrates a large modulation depth of 11.4% and a low saturation intensity of 31.12 MW cm −2 . The output pulse width is ∼398 fs with a spectral bandwidth of ∼7.45 nm. Stable bound state solitons are also generated with the GO-COOH based SA. Our results show that the GO-COOH is a promising SA for femtosecond pulse generation.

羧基氧化石墨烯锁模飞秒光纤激光器

我们报告了一种新型的氧化石墨烯衍生的纳米材料,基于羧基的氧化石墨烯(GO-COOH)的可饱和吸收剂(SA),用于超短脉冲的产生。我们的基于GO-COOH的SA表现出11.4%的大调制深度和31.12 MW cm -2的低饱和强度。输出脉冲宽度约为398 fs,光谱带宽约为7.45 nm。稳定的结合态孤子也可以通过基于GO-COOH的SA生成。我们的结果表明,GO-COOH是飞秒脉冲产生的有希望的SA。
