将使用改进的斩波器的热管理Z扫描与利用具有常见校准材料二硫化碳的脉冲拾取器进行比较，然后在λ = 800 nm处扩展到不同溶剂中的氧化石墨烯（GO）。使用飞秒激光激发的蒸馏水中的GO对于纳米颗粒产生（-2.7 +/- .4）x 10（-15）cm（2）/W的值，并且对于微米尺寸的颗粒产生（-1.6 +/- .6）x 10（-15）cm（2）/W的值。使用改进的斩波器的开孔Z扫描结果显示没有实验差异。(C)2016美国光学学会
Thermally managed Z-scan using a modified chopper was compared to the utilization of a pulse picker with the common calibration material carbon disulfide and then extended to graphene oxide (GO) in different solvents at lambda = 800 nm. GO in distilled water using femtosecond laser excitation yielded a value of (-2.7 +/- .4) x 10(-15) cm(2)/W for nanometer particles and (-1.6 +/- .6) x 10(-15) cm(2)/W for micrometer-sized particles. Openaperture Z-scan results using the modified chopper showed no experimental difference. (C) 2016 Optical Society of America
