Research using FELBE
The free-electron laser (FEL) at ELBE (= FELBE) delivers coherent, intense, spectrally narrow, and pulsed beams in the mid and far infrared regions. The radiation is spectrally tunable in the wavelength range from 4 µm to 250 µm with pulse durations in the picosecond to sub-picosecond range and energies of several µJ per pulse.
FELBE radiation is used for a variety of experimental fields
- Investigation of semiconductors and quantum structures
- Investigation of soft matter and biological materials
- Research on superconductors
- THz-induced phase transitions
- Cyclotron resonance measurements in pulsed magnetic fields
- Electron paramagnetic resonance
The following experimental techniques are available
- Pump-probe experiments in the ps regime
Synchronized tabletop laser systems are also available for two-color pump-probe experiments.
- Optical sideband generation
- Scattering scanning near-field microscopy (s-SNOM)
- Time-resolved photoluminescence
- Infrared and far-infrared spectroscopy in pulsed magnetic fields
