TLDR
In this article, a generalized phase-matching model is proposed for the generation of high-order harmonics using laser pulse energies in the few-μJ range at high repetition rates.Abstract:
We investigate the generation of high-order harmonics using laser pulse energies in the few-μJ range at high repetition rates. We analyse how the conversion efficiency is influenced by the tight focusing geometry required for the generation of high-order harmonics under these conditions. A generalized phase-matching model allows us to discuss macroscopic phase effects independent of focal length. We present experimental results using the example of a 100 kHz laser system to generate harmonics up to the 27th order in Ar with a photon flux up to 3 × 109 photons s−1 into one harmonic order. High-repetition-rate femtosecond or even attosecond light sources open new possibilities for a broad range of applications such as time-resolved photoelectron spectroscopy and microscopy in the extreme ultraviolet regime.read more

TL;DR: In this article, the scaling laws for the main physical quantities of high harmonic generation were discussed and the limiting effects of dephasing, absorption and plasma defocusing were analyzed, and it was shown that phase-matched and absorption-limited high-order harmonics can be achieved even for very small focal spot sizes using a target gas provided with an adequately high density.

Kinetics and kinematics for translational motions in microgravity during parabolic flight.
TL;DR: The goal is to combine kinetic and kinematic data to examine translational motions during microgravity adaptations to encourage fine-control motions as these reduce the risk of injury and increase controllability.

Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.
