Sum
frequency generation (up-conversion) method is used in the FOG100 femtosecond optically
gated (FOG) fluorescence kinetic measurement system to achieve a temporal resolution
better than 100 femtoseconds. The FOG100 is a first commercially available complete system
for femtosecond lifetime and kinetic spectroscopy measurements. The system has been designed to be matched with any type of femtosecond laser operating at
> 1 kHz pulse repetition rate.
The system includes optical and mechanical components installed on a breadboard; monochromator; selected photon counting PMT; electronic unit; PC software, installation and test measurements. The electronic unit contains photon counter, step motor driver, computer controlled PMT power supply and low voltage power supplies.

what our customers tell:
"We have bought main component of our femtosecond
laser system TISSA 50 a couple of years ago and quite happy with
it. TISSA50 fs generator is pumped by Coherent Ar laser, Innova 316P. This combination
works fine, we have ~60 fs pulses without compressor and the whole system is in working
condition after one hour of warming up.
Next is up-conversion system, FOG100. I was impressed by the way it was installed. Two
fellows came, assembled generator and up-conversion in 4 days and in 5th day I have got
fluorescence decay of my sample together with answer I was trying to obtain using other
techniques during one year. Certainly, it’s excellent instrument.
