Transient Absorption Spectroscopy

Transient Absorption Spectroscopy (TAS) for the measurement of the absorption evolution of charge carriers in the opto-electronic materials. The working principle (left), fs-TAS facility (middle and ns-TAS (right)

Terahertz Time-Domain Spectroscopy


Terahertz Time-Domain Spectroscopy (THz-TDS) for the measurement of the reflective or transmissive transitions of charge carriers within opto-electronic materials.

Femtosecond Stimulated Raman Spectroscopy 

Femtosecond Stimulated Raman Spectroscopy (FSRS) is an advanced ultrafast spectroscopic technique that enables the study of molecular dynamics with high temporal and spectral resolution, providing insights into chemical reactions and material properties on the femtosecond timescale.

Up-/Down-conversion Fluorescence Spectroscopy

Up-/Down-conversion Fluorescence Spectroscopy using femtosecond laser pulses allows for time-resolved measurement of fluorescence with femtosecond time resolution, as the temporal resolution is primarily determined by the pulse duration of the laser rather than electronic limitations. This technique is ideal for studying ultrafast processes in fluorescent materials.
