Abstract

Described is a system for inducing and detecting multi-photon processes, in particular multi-photon fluorescence or higher harmonic generation in a sample. The system comprises a dynamically-controllable light source, said dynamically-controllable light source comprising a first sub-light source, said first sub-light source being electrically controllable such as to generate controllable time-dependent intensity patterns of light having a first wavelength, and at least one optical amplifier, thereby allowing for active time-control of creation of multi-photon-excitation. The system further comprises a beam delivery unit for delivering light generated by said dynamically-controllable light source to a sample site, and a detector unit or detector assembly for detecting signals indicative of said multi-photon process, in particular multi-photon fluorescence signals or higher harmonics signals.
