Measurements of ultrafast transient processes, temporal durations in the picosecond and femtosecond regime, are made possible by pump probe absorption spectroscopy. Such an setup has been implemented at CSIR National Laser Centre applied to investigate energy transfer processes different parts photosynthetic systems. In this paper we report on our first results obtained with Malachite green as a benchmark. was chosen because lifetime its excited state is well known. We also present experimental light-harvesting complexes samples prepared from spinach leaves. Various wavelengths range 600–680 nm were used; white light continuum spanning 420–700 nm. The described detail paper. Results these consistent those expected achieved other researchers field.
