Transient Absorption Spectrometer, Femtosecond Pump-Probe Spectroscopy

Newport’s Transient Absorption Spectrometer (TAS) is a state-of-the-art instrument for femtosecond pump-probe spectroscopy. In an ultrafast pump-probe experiment using TAS, the sample of interest is excited by the pump pulse and the dynamics of the sample are monitored as a function of time at many wavelengths by a white-light supercontinuum probe routed with reflective optics to minimize chirp. The probe light is sensed as a function of wavelength by the combination of a fiber coupled multichannel detector and imaging spectrograph, offering the optimum combination of sensitivity and dynamic range. Since TAS was designed with the scientific research community in mind, there is substantial flexibility in the configuration of the optical layout, detection range, and spectral resolution. TAS can be configured for Ti:Sapphire based amplifiers with repetition rates ranging from 10 Hz to 8 kHz and comes with straightforward LabView®-based software.
