The fundamental for the Up-conversion is taken from MAITAI laser (Spectra Physics, ~120 fs, 80 MHz, 2.5 W at 800 nm) can be frequency doubled and is used to excite the sample and the frequency mixing is performed in a non-linear optical crystal, e.g. BBO (β-Borium Borate). The time evolution of the fluorescence is obtained by delaying the probe pulse using a mechanical delay stage. This technique of Fluorescence Up-conversion is used to study photo-physical properties of excited states.
