Phase matching of high harmonic generation in the soft and hard X-ray regions of the spectrum
Tenio Popmintchev, Ming-Chang Chen, Alon Bahabad +6
We show how bright, fully coherent, hard x-ray beams can be generated through nonlinear upconversion of femtosecond laser light. By using longer-wavelength mid-infrared driving las…

Generation of Spatially Coherent Light at Extreme Ultraviolet Wavelengths
Randy A. Bartels, Ariel Paul, Hans Green +7
We present spatial coherence measurements of extreme-ultraviolet light generated using the process of high-harmonic upconversion of a femtosecond laser. Using a phase-matched hollo…
