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
