This two-photon fluorescence image sequence shows the formation of a localized photothrombotic clot in a surface arteriole. The fluctuating, streaked appearance of the vessels is due to the motion of red blood cells and indicates flow. A saturated white strip at the top of the frame indicates irradiation with 523-nm light. Clot material is formed just downstream from the irradiated region.
