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 5 µm to 250 µm with pulse durations in the picosecond to sub-picosecond range and energies of up to several µJ per pulse.
