一种基于石墨烯的可饱和吸收镜的制备方法
摘要：
本发明公开了一种基于石墨烯的可饱和吸收镜的制备方法，具体步骤为：把石墨烯加入到水或氯仿中，对其进行超声分散，制备得到石墨烯浓度为4-20mg/mL的分散液；将石墨烯分散液离心得上清液；若上述溶剂为水，则将质量分数为10%-20%的聚乙烯醇水溶液加至上述上清液中混合，若上述溶剂为氯仿，则将质量分数为8%-20%的聚甲基丙烯酸甲酯氯仿溶液加至上述上清液中混合；将上述混合液旋涂于增透镜或高反镜上，制得可饱和吸收镜。本发明采用石墨烯作为可饱和吸收镜，可以用于不同波长；本发明制备过程简便易行，成本低廉，易于实际应用。
摘要（英）：

The invention discloses a preparation method for a graphene-based saturable adsorption mirror. The preparation method comprises the following steps: adding graphene into water or chloroform to carry out ultrasonic dispersion on the graphene, and preparing to obtain a dispersion liquid with the graphene concentration of 4-20mg/ml; centrifuging the graphene dispersion liquid to obtain a supernatant; adding a polyethylene alcohol aqueous solution with the mass fraction of 10%-20% into the supernatant for mixing if the solvent is water, adding a polymethylmethacrylate chloroform solution with themass fraction of 8%-20% into the supernatant for mixing if the solvent is chloroform; and carrying out spin-coating on an increase lens or a high reflective mirror by the mixed solution to obtain a saturable adsorption mirror. The invention uses graphene as a saturable adsorption mirror for different wavelengths; and the preparation method disclosed by the invention is simple and accurate with low cost, and is easy for practical use.
