- Microphotoluminescence (500nm spatial resolution)
- Single photon counting
- Polarization-resolved spectroscopy using Müller matrix analysis
- Magnetic field dependent spectroscopy up to 3.5T
- Raman spectroscopy
- Optical gain spectroscopy in processed and unprocessed samples (Hakki-Paoli, transmission method, variable stripe length method)
Optical imaging and novel imaging systems
- Standard spectroscopic optical coherence tomography (OCT and SOCT)
- Digital and photorefractive holography
