fusionNear Term Laser Space Propulsion to Move Twenty Times Faster in the Solar System

This is an update of the system under development by John Brophy and his team and it will use a kilometer-scale, multi-hundred-megawatt phased-array laser to beam power to a vehicle that converts it to electrical power for a multi-megawatt electric …

laserDiffracted solar sail

There is a NASA NIAC study to improved laser pushed sails with advanced diffracted solar sail. Advanced diffractive films may afford advantages over passive reflective surfaces for a variety space missions that use solar or laser in-space propulsion. Three cases …

Les Johnson of the NASA Marshall Space Center provides a 37-page presentation on solar sails covering the technical details, past projects and future projects. Near-term work is with various cubesats and solar sails. Near Earth Asteroid Scout The Near Earth …

3dNASA laser wire 3D printing of rocket nozzles is much cheaper and five times faster

A new process called Laser Wire Direct Closeout (LWDC) was developed and advanced at NASA to build a less-expensive rocket nozzle in significantly less time. LWDC is a different process than most 3-D printing technologies, which are powder-based and fabricated …

laserAnalog quantum simulation based on laser-trapped circular Rydberg atoms

State-of-the-art techniques make it possible to build a spin-chain quantum simulator based on laser-trapped circular Rydberg atoms. This simulator combines the flexibility of atomic lattices and the individual atomic observable read-out typical of ion trap, together with the strong dipole-dipole …

energyPrototype for two beam laser fusion system within a decade if no major hurdles arise

Dramatic advances in laser technology are close to making the two-laser approach feasible, and a spate of recent experiments around the world indicate that an ‘avalanche’ fusion reaction could be triggered in the trillionth-of-a-second blast from a petawatt-scale laser pulse, …

economic impactBreakthroughs could make commercial laser nuclear fusion through billion times improvements in yield

Two recent scientific breakthroughs have opened a new way to laser fusion reactions according to startup HB11 Energy. It involves the reaction between hydrogen H and the boron isotope 11 (HB11) as uncompressed solid state fuel within an extremely high …
