FEL oscilators & IR-FEL: Session-5
- Aliaksei Halavanau (SLAC National Accelerator Laboratory)
We present the first commissioning results of the XFEL laser oscillator (XFELO) demonstrator project, a joint European XFEL and DESY effort. XFELOs promise unprecedented coherence, stability and Brilliance in the hard X-ray regime. Their successful realization would mean a leap forward for the
field of FELs, opening new experimental opportunities [1] and facilitating the notoriously demanding...
Cavity-based free-electron lasers (CBXFELs) offer the potential to significantly enhance the stability and coherence of FELs. The CBXFEL project is a collaborative effort between SLAC, Argonne, and RIKEN, focused on constructing a 65-meter rectangular X-ray cavity at the LCLS. The primary goal is to demonstrate low-loss cavity ring-down and, ultimately, achieve two-pass FEL gain. This talk...
Despite tremendous progress in x-ray free-electron laser science over the last decade, future applications still demand fully coherent, stable X rays that have not been demonstrated in existing X-ray FEL facilities. Cavity-based x-ray free electron lasers (CBXFELs) such as the x-ray regenerative amplifier FEL (XRAFEL) and the XFEL oscillator (XFELO) are poised to revolutionize the landscape....
Since 2013 the infrared FEL at the Fritz Haber Institute (FHI FEL) has been providing intense, pulsed mid-infrared (MIR) radiation continuously tunable from <3 μm to >50 μm for in-house users. In 2023 an additional short-Rayleigh-range far-infrared (FIR) FEL was commissioned lasing from <5 μm to >170 μm. In addition, a 500 MHz kicker cavity has been installed downstream of the electron...
