We have developed a new detection mechanism for ultrabroadband multicolor fluorescence detection using an ultrafast supercontinuum white light source without spectral filtering to simultaneously excite different fluorophores. A nonlinear photonic crystal fiber was utilized in conjunction with a femtosecond laser to generate the supercontinuum. A time-resolved detector was tested to detect the whole spectrum fluorescence while gating out the excitation white light in the time domain.
