Femtosecond Pump-Probe Spectroscopy

Описание к видео Femtosecond Pump-Probe Spectroscopy

The Femtosecond Pump Probe Spectrometer is used to measure absorption of species in the excited state. It is sometimes called two dimensional spectroscopy because it provided temporal as well as spectral information. Pump beam at a particular wavelength is pulsed on a sample just femtoseconds before another broad spectrum probe beam is pulsed on the sample. The probe beam is then analyzed for absorption by wavelength.
