This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We are trying to measure two-photon absorption cross sections using the photon counting histogram (PCH). PCH analysis can tell us the molecular brightness and average particle number of our fluorescent sample. Using the molecular brightness and quantum yield we can then calculate the cross section relative to a known standard, fluorescein.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。我们尝试用光子计数直方图（PCH）测量双光子吸收截面。PCH分析可以告诉我们荧光样品的分子亮度和平均粒子数。使用分子亮度和量子产率，我们可以计算相对于已知标准荧光素的横截面。
