I report on the measurement of threshold energy fluence for optical limiting of nanosecond and microsecond pulses in a high-performance carbon suspension known as Defence Research Establishment Valcartier carbon black suspension (CBS)-100. Thresholds as low as 24-mJ/cm(2) (nanosecond regime) and 100-mJ/cm(2) (microsecond regime) have been obtained. The measurement technique, based on an f/20 optical system and a small analysis aperture, has been tested by measurement of reverse saturable absorber materials and other carbon suspensions whose properties can be found in the technical literature. A factor of merit has emerged from these measurements that could be used to order by limiting performance the different types of carbon suspension. In this ordering, CBS-100 appears as the best choice in the set of suspensions tested for short and long pulses.
我报告了在一种名为国防研究机构瓦尔卡蒂埃炭黑悬浮液（CBS）-100的高性能碳悬浮液中，对纳秒和微秒脉冲进行光学限幅的阈值能量通量的测量。已获得低至24 mJ/cm²（纳秒 regime）和100 mJ/cm²（微秒 regime）的阈值。基于f/20光学系统和小分析孔径的测量技术，已通过对反向饱和吸收材料和其他碳悬浮液的测量进行了测试，其特性可在技术文献中找到。这些测量得出了一个品质因数，可用于按限幅性能对不同类型的碳悬浮液进行排序。在这种排序中，CBS-100在测试的短脉冲和长脉冲悬浮液组中似乎是最佳选择。
