Frequency and Polarization Mixing in the X-ray Regime
3. Quantum Design Concept
By using polarization and frequency mixing to create a complex bi-color mid-infrared driving laser field, the extreme nonlinear optical process of high harmonic generation upconverts light in the X-ray regime. Remarkably, this upconversion also transfers the angular momentum properties of the driving light into the newly generated light through exquisite attosecond control of electron wavefunctions.
