抄録

Multiphoton fluorescence microscopy offers ability of imaging thick samples with enhanced longitudinal resolution, but suffers from issues of photobleaching and phototoxicity. It has been known that three-photon absorption of DNA is one of the causes of phototoxicity. Here, we apply coherent control to enhance the contrast between the two-photon absorption of fluorescent label and the three-photon absorption of biomaterial with engineered cost function, leading to effectively reduced three-photon absorption without loss of valuable two-photon fluorescence.
