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…

High-order harmonics with frequency-varying polarization within each harmonic
Avner Fleischer, Ofer Kfir, Pavel Sidorenko +1
We predict high-order harmonics in which the polarization within the spectral bandwidth of each harmonic varies continuously and significantly. For example, the interaction of coun…
