The Advanced Light Source (ALS) is a third-generation light source in operation since 1993. This light source is providing state-of-the-art performance to more than 40 beamlines and their users, due to the upgrades that have been completed over the last few years. The storage ring upgrade project that is developed here will allow the ALS to provide the 40 beamline users with higher photon beam brightness...
We model soft x-ray high harmonic generation and propagation driven by mid-infrared lasers. We find that multi-cycle laser pulses are ideal for generating shorter bright isolated attosecond pulses via time-gated phase-matching in high-density extended media.
Using a 3.9µm driving laser focused into a high-pressure gas-filled waveguide, we generate bright, phase matched, fully spatially coherent high harmonic beams in the keV region for the first time.
Using a 3.9μm driving laser focused into a high-pressure gas-filled waveguide, we generate bright, phase matched, fully spatially coherent high harmonic beams in the keV region for the first time.
We present a unified picture of phase matching of high harmonic upconversion spanning the electromagnetic spectrum from the VUV to keV, combining both microscopic and macroscopic physics. We validate this picture with experiment and theory.
We generate fully spatially coherent soft x-ray beams in the water window region of the spectrum using phase matched high harmonic upconversion of a 2 µm driving laser.
Single fed, high gain and lightweight patch arrays of size 12"times9" are designed and proposed for integration with a harmonic portable RFID radar so as to track the behavioral patterns of invasive Emerald Ash Borer insect. Serial interconnections of the array elements are tapered in order to suppress sidelobe level. With these additions, the proposed harmonic insect tracking radar system...
By tightly focusing a high repetition rate (50 kHz), compact, femtosecond laser system with low pulse energy (25 muJ), we demonstrate fully phase matched, fully spatially coherent, 50 kHz high harmonic beams for the first time.
We demonstrate that using longer-wavelength driving light in high-order harmonic generation requires moderately ionized larger-density atoms to perfectly phase match the process, scaling conventional phase matching at low ionization to extremely high photon energies.
