我们采用垂直蒸发技术将单壁碳纳米管（SWCNT）嵌入聚合物（乙烯醇）中制备可饱和吸收剂。利用瞬态吸收实验装置，测定了两种吸收剂的快速恢复时间常数分别为250fs和1.13ps。在1060nm处，吸收剂的饱和强度为300-400μJ /cm2，调制深度高达3.5%。
We employed a vertical evaporation technique to fabricate saturable absorbers by embedding single wall carbon nanotubes (SWCNT) in polymer (vinylalcohol). Two fast recovery time constants, 250fs and 1.13ps, respectively, were measured for the absorbers using a transient absorption experimental setup. The saturation intensity of the absorber was found to be 300–400μJ/cm2at 1060nm, and a modulation depth as high as 3.5% was achieved.
