Ultrafast excitation of quantum dots with a fibre laser for deep tissue imaging
MetadataShow full item record
Fluorescence from three photon absorption was observed in CdSe quantum dots excited with ultrashort pulses from a telecom band Erbium fibre laser. Reduced scattering at longer wavelengths makes this approach interesting for deep tissue imaging.
