| Research Abstract |
We have demonstrated that the selective excitation and de-excitation (or re-excitation) method of a fluorescence molecule using femtosecond pulse train with multi colors, which is applicable to highly selective fluorescence imaging of a biological cell and its extra cellular matrix. We constructed the pulse shaping system using two dimensional spatial light modulator and studied suitable pulse trains for the electronic and vibrational character of a target fluorescence molecule.
