Plasma-Based Laser Pulse System: Higher Power, Sharper Wavefront
Princeton Docket # 17-3296, 17-3311, 17-3333Current laser systems are inherently brilliance-limited by the ability of the internals to resist damage by the laser. To overcome this thermal threshold, researchers at the Princeton Plasma Physics Laboratory have invented techniques to improve the current laser amplifiers based on Raman instability in plasmas....

Feedback Control of Azimuthal Oscillations in Hall Thrusters: Enhanced Thruster Efficiency and Performance
Princeton Docket # 12-2808 Researchers at Princeton Plasma Physics Laboratory have developed a novel method to achieve feedback control of low-frequency azimuthal waves (rotating spoke oscillation) in the ExB discharge of a Hall thruster. This technology will enhance thruster efficiency and performance. The Hall thruster is a plasma-based propulsion...
