Ultrafast transient holographic microscopy
WebUltrafast Spectroscopy Transient Absorption Spectroscopy (Pump-probe) Transient absorption spectroscopy uses two laser pulses, a strong pump and a weak probe which are overlapped in the sample. The linear absorption of the sample is recorded as the probe is delayed in time relative to pump using an optical delay line. Web14 Apr 2010 · Transient absorption microscopy was employed to image charge carrier dynamics in epitaxial multilayer graphene. The carrier cooling exhibited a biexponential decay that showed a significant dependence on carrier density.
