Session 6: FEL Oscillators and Infrared FEL (IR-FEL)

Contributed Oral Presentation

The cavity-based XFEL (CBXFEL) is a novel X-ray source based on an X-ray Free-Electron Laser (XFEL) encased in an optical cavity. This concept, when built, will offer substantial improvements in X-ray brightness and coherence compared to existing high-gain SASE sources. A joint project is underway at SLAC National Accelerator Laboratory, in collaboration with Argonne National Laboratory and...

Session 6: FEL Oscillators and Infrared FEL (IR-FEL)

Contributed Oral Presentation

High harmonic generation (HHG) has emerged as a powerful method for producing coherent femtosecond-to-attosecond light in the VUV, EUV, and X-ray regions. Since the harmonic cutoff energy and the upconversion phase matching limits increase with the driving laser wavelength, mid-infrared (MIR) drivers are uniquely advantageous for extending the emission toward soft X-ray wavelengths, and...
