The state-of-the art setup for optical characterization includes Silicon and InGaAs diode array photodetectors, InGaAs photomultiplier, spectrometers, excitation sources (CW and pulsed lasers), and optical cryostats.

High-resolution Raman scattering setup is capable of measuring inelastic light scattering with spectral resolution of 0.25 cm^-1 and spectral shift of the laser line better when 10 cm^-1
