Stability of target irradiation for high-repetition rate direct-drive facilities

EPJ Web of Conferences, 2013
The illumination of a spherical target for Inertial Confinement Fusion is studied in the direct-drive approach. Three main sources of laser parameter fluctuation are taken into account, and a statistical analysis of the illumination configuration has ...

Scaling of black silicon processing time by high repetition rate femtosecond lasers

MATEC Web of Conferences, 2013
Surface texturing of silicon substrates is performed by femtosecond laser irradiation at high repetition rates. Various fabrication parameters are optimized in order to achieve very high absorptance in the visible region from the micro-structured silicon

A high-repetition rate attosecond light source for time-resolved coincidence spectroscopy

Nanophotonics, 2020
Attosecond pulses, produced through high-order harmonic generation in gases, have been successfully used for observing ultrafast, subfemtosecond electron dynamics in atoms, molecules and solid state systems.

Thermoelastic study of nanolayered structures using time-resolved x-ray diffraction at high repetition rate

, 2013
We investigate the thermoelastic response of a nanolayered sample composed of a metallic SrRuO3 (SRO) electrode sandwiched between a ferroelectric Pb(Zr0.2Ti0.8)O3 (PZT) film with negative thermal expansion and a SrTiO3 substrate.

Compact, high-repetition-rate source for broadband sum-frequency generation spectroscopy

APL Photonics, 2017
We present a high-efficiency optical parametric source for broadband vibrational sum-frequency generation (BB-VSFG) for the chemically important mid-infrared spectral range at 2800–3600 cm−1 to study hydrogen bonding interactions affecting the structural

Ultrafast, high repetition rate, ultraviolet, fiber based laser source: application towards Yb+ fast quantum-logic

, 2016
Trapped ions are one of the most promising approaches for the realization of a universal quantum computer. Faster quantum logic gates could dramatically improve the performance of trapped-ion quantum computers, and require the development of suitable ...

High repetition rate femtosecond laser heat accumulation and ablation thresholds in cobalt-binder and binderless tungsten carbides [PDF]

, 2019
Femtosecond (fs) laser ablation has been studied for the potential of fast, high precision machining of difficult-to-machine materials like binderless tungsten carbide. Obstacles that have limited its efficiency include melting from heat accumulation (HA)
