Low-latency enhanced light curtain for safe laser power beaming
LASEFree space optical power beaming typically involves the use of a high-power laser with irradiance that far exceeds direct exposure safety limits. Therefore, to ensure safe operation of the power beaming system, the area surrounding the beam must be ...

Analysis and design of safe laser power beaming systems
LASELaser power beaming comes with safety risks that arise from accidental exposure to intense radiation from the beam. This paper describes PowerLight Technologies’ approach to developing its safety architecture, including definition of a hazard tracking ...

Direct beam hazard analysis of large beam diameters for laser power beaming
Journal of laser applications, 2018The mission lifetime for unmanned aerial vehicles and unmanned ground vehicles (UGVs) might potentially be increased by transmitting electrical power wirelessly, using a laser source and a photovoltaic array receiver, but such laser power beaming (LPB ...

High-power CO2 laser-beam monitor
Review of Scientific Instruments, 1978A diagnostic system for measuring the beam power and quality of a high-power cw CO2 electro-aerodynamic laser is described. A ZnSe beamsplitter was employed to split off a small fraction (0.5%) of the main laser beam for diagnostic purposes. The low-power beam was split again to provide two beams for power and energy-distribution measurements ...

Improving Metrics for Laser Power Beaming
2024 IEEE Wireless Power Technology Conference and Expo (WPTCE)Important performance metrics for laser power beaming in three areas are described: efficiency, size- and weight-specific power, and the reaction time plus stand-off distance requirements for active safety sensing.

Wireless power beam device using microwave power transfer
2014 IEEE Wireless Power Transfer Conference, 2014The authors proposed a novel WPT system using ceramic dielectric resonators. Unloaded Q of ceramic resonator is several tens of thousands depending on the material. Thus, we can expect much longer transmission distance by using ceramic resonator. It was confirmed that the power transfer of this system was conducted by a combination both of coupling in ...

High-power beam control: results-to-date and relevance to power beaming
SPIE Proceedings, 1997Over the past fifteen years, the mid-infrared advanced chemical laser (MIRACL) and SeaLite beam director (SLBD) have been completed, moved to the High Energy Laser System Test Facility (HELSTF) at White Sands Missile Range, New Mexico, and integrated into the largest and most powerful high energy laser system in the U.S.

Proceedings of the IRE, 1938
The general characteristics of the ideal output tube for broadcast receivers are discussed briefly with respect to specific electrical and acoustical requirements. Considerations of practical power-tube design indicate that the tube most nearly approaching the ideal characteristics is one having an accelerating grid (screen) and a control grid which ...
