Unintended consequences with laser nudging or re-entry of satellites
Autor: Egor Y. Loktionov, Elizaveta Sharaborova, Claude R. Phipps
Publikováno v: Acta Astronautica. 181:439-444
We measured the impulse coupling coefficient Cm (target momentum per joule of the incident laser light) and ejecta velocity vE with glass-covered Si solar (photovoltaic) cells following the irradiation by repetitive 71 ps, 1064 nm laser pulses at flu

Publikováno v: Acta Astronautica. 170:637-651
The ever increasing number of orbital objects since 1957 raises numerous questions concerning future sustainability of space. Among the 34,000 objects larger than 10 cm in orbit, 20,000 only are cataloged. These cataloged objects include roughly 2000

Is laser space propulsion practical?: review
Autor: Claude R. Phipps, Gilles Tahan, S. A. E. Boyer, E. Y. Loktionov, C. Bonnal, Elizaveta Sharaborova
Publikováno v: Applied optics
Applied optics, Optical Society of America, 2021, 60 (31), pp.H1. ⟨10.1364/AO.434245⟩
In this paper, we review practical limitations to laser space propulsion that have been discussed in the literature. These are as follows: (1) thermal coupling to the propelled payload, which might melt it; (2) a decrease in mechanical coupling with

A spaceborne, pulsed UV laser system for re-entering or nudging LEO debris, and re-orbiting GEO debris
Autor: Christophe Bonnal, Claude R. Phipps
Publikováno v: Acta Astronautica. 118:224-236
Among the problems raised by the presence of debris in Earth Orbit, the question of large derelict satellites in Geostationary Orbit (GEO) is of major importance. More than 1000 defunct GEO satellites cruise in the vicinity of this unique orbit and p

Laser Ablation Propulsion and Its Applications in Space
Autor: Claude R. Phipps
Publikováno v: Advances in the Application of Lasers in Materials Science ISBN: 9783319968445
Where lasers shine is in propelling a remote object using a space-based mother ship with an onboard laser. In some cases, there is no other reasonable choice. These cases include small low Earth orbit (LEO) debris reentry, large LEO debris nudging to

International audience; New data on some materials at 80ps pulse duration and 1057 nm wavelength give us the option of proportionally combining them to obtain arbitrary values between 35 (aluminum) and 800 N/MW (POM, polyoxymethylene) for momentum co

Fs Laser-Induced Plasmas from Energetic Polymers: Towards Micro-Laser Plasma Thruster Application
Autor: Alexander Wokaun, Thomas Lippert, Claude R. Phipps, Alexandra Palla Papavlu, Lukas Urech, Jörg Hermann
Publikováno v: Plasma Processes and Polymers. 13:611-622
The micro-laser plasma thruster (μ-LPT) is a device aimed at orienting and repositioning small satellites above the atmosphere. These devices are based on IR diode lasers utilized for the ablation of polymers and production of thrust for the control
