		FOG100 Fluorescence Up-Conversion System


		Sum frequency generation (up-conversion) is used in the femtosecond optically gated (FOG) fluorescence kinetic measurement system FOG100 to achieve a temporal resolution of better than 100 femtoseconds. FOG100 is the first complete measurement system for femtosecond and picosecond lifetime and kinetic spectroscopy. It has been designed to be matched with any type of femtosecond oscillator or oscillator - amplifier system operating at > 1 KHz pulse repetition rate.


		The FOG100 includes optical unit together with 2-ns optical delay line; single or double monochromator; selected photon counting PMT; electronics; Windows based Lumex 3.1 software; installation, test measurements and personnel training.


		ExciPro Femtosecond Absorption Pump-Probe System ExciPro-D The ExciPro-D system is used in femtosecond or picosecond pump-probe absorption spectroscopy for transient absorbance (optical density) changes measurements. Two photodiode arrays are placed after an imaging spectrometer to measure probe and reference spectra, originating from femtosecond white light (continuum) generator. Photoinduced optical density changes are calculated from probe and reference spectra measured before and after the sample excitation.
