摘要: In this work we present a femtosecond stimulated Raman scattering system. The setup is based on a commercial femtosecond laser system supplemented by a pair of travelling-wave optical parametric amplifiers. One the parametric amplifiers used to generate the femtosecond actinic pump pulses, whereas the output the other (high-power) amplifier undergoes a combination spectrally narrowed second harmonic generation in a long non-linear crystal and subsequent spectral filtering for the generation narrowband pulses. Chirped white light supercontinuum as the Raman probe. offers tunability pulses the 400–800 nm range, temporal resolutions ca. 6 cm –1 70 fs, respectively. We the basic technical aspects the system along with data acquisition signal retrieval techniques. characterize exploring the time-resolved vibrational dynamics the S 2 (1 1 B u + ) S (2 A g – excited states β-carotene.
