High quantum efficiency parametric amplification via hybridized nonlinear optics
Noah Flemens, Dylan Heberle, Jiaoyang Zheng +5
Parametric amplifiers have allowed breakthroughs in ultrafast, strong-field, and high-energy density laser science and are an essential tool for extending the frequency range of po…
Hermitian Nonlinear Wave Mixing Controlled by a PT-Symmetric Phase Transition
Noah Flemens, Jeffrey Moses
While non-Hermitian systems are normally constructed through incoherent coupling to a larger environment, recent works have shown that under certain conditions coherent couplings c…
Non-Hermitian Dynamics Mimicked by a Hermitian Nonlinear System
Noah Flemens, Nicolas Swenson, Jeffrey Moses
We illustrate that a Hermitian nonlinear optical system consisting of hybridized parametric amplification and second harmonic generation mimics non-Hermitian evolution dynamics. Os…
High-energy mid-infrared sub-cycle pulse synthesis from a parametric amplifier
Houkun Liang, Peter Krogen, Zhou Wang +8
High-energy, carrier-envelope phase (CEP)-stable, sub-cycle, mid-infrared (mid-IR) pulses can provide unique opportunities of exploring phase-sensitive strong-field light-matter in…
Multi-mJ, kHz, 2.1-m OPCPA for high-flux soft X-ray high-harmonic radiation
Kyung-Han Hong, Chien-Jen Lai, Jonathas Siqueira +5
We report on a multi-mJ 2.1-m OPCPA system operating at a 1-kHz repetition rate, pumped by a picosecond cryogenic Yb:YAG pump laser, and the phase-matched high-flux high-harmoni…
High-order harmonic generation in Xe, Kr, and Ar driven by a 2.1-μm source: high-order harmonic spectroscopy under macroscopic effects
Kyung-Han Hong, Chien-Jen Lai, Vasileios-Marios Gkortsas +5
We experimentally and numerically study the atomic response and pulse propagation effects of high-order harmonics generated in Xe, Kr, and Ar driven by a 2.1-μm infrared femtosecon…
