Ultrafast transient absorption spectrometer The spectrometer is highly versatile and flexible and can be easily configured for different optical techniques.
In general, in transient absorption experiments the pump pulse interacts with the system of interest, after which the transient absorption change in the sample is monitored by a time-delayed probe beam. The transient absorption spectrum contains clues to both structural information and dynamics. The TAS device can operate in two spectral regimes covering probe wavelengths from 400 nm to 800 nm or 800 nm to 1600 nm. The optical delay line provides femtosecond temporal resolution over a range as wide as 3.2 ns. Application note (Newport Corp) pdf
