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…
Phase-Matching of High-Order Harmonics Driven by Mid- Infrared Light
Tenio Popmintchev, Ming-Chang Chen, Oren Cohen +4
We demonstrate that phase-matched frequency upconversion of ultrafast laser light can be extended to shorter wavelengths by using longer driving laser wavelengths. Experimentally,…
Bright Coherent Ultrahigh Harmonics in the keV X-Ray Regime from Mid-Infrared Femtosecond Lasers
Tenio Popmintchev, Ming-Chang Chen, Dimitar Popmintchev +17
High harmonic generation traditionally combines ~100 near-infrared laser photons, to generate bright, phase matched, extreme ultraviolet beams when the emission from many atoms add…
1-MHz operation of 1.7-cycle multiple plate compression at 35-W average output power
Takuya Okamoto, Yoji Kunihashi, Yasushi Shinohara +3
We generated 1.7-cycle and 35-J pulses at a 1-MHz repetition rate by using two-stage multiple plate continuum compression of Yb-laser pulses with 80-W average input power. By ad…
Spatially resolved spectral phase interferometry with isolated attosecond pulse
Hiroki Mashiko, Ming-Chang Chen, Koji Asaga +5
We characterized spatially resolved spectral phase interferometry with an isolated attosecond pulse (IAP). The measured spatial-spectral interferogram and spectral interference fri…
Generation of Bright Isolated Attosecond Soft X-Ray Pulses Driven by Multi-Cycle Mid-Infrared Lasers
M. -C. Chen, C. Hernández-García, C. Mancuso +11
High harmonic generation driven by femtosecond lasers makes it possible to capture the fastest dynamics in molecules and materials. However, to date the shortest attosecond (as) pu…
