Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass.

The US has finished constructing a huge physics experiment aimed at recreating conditions at the heart of our Sun. The US National Ignition Facility is designed to demonstrate the feasibility of nuclear fusion, a process that could offer abundant clean energy. The lab will kick-start the reaction by focusing 192 giant laser beams on a tiny pellet of hydrogen fuel. To work, it must show that more energy can be extracted from the process...

A major hurdle to producing fusion energy using lasers has been swept aside, results in a new report show. The controlled fusion of atoms - creating conditions like those in our Sun - has long been touted as a possible revolutionary energy source. However, there have been doubts about the use of powerful lasers for fusion energy because the "plasma" they create could interrupt the fusion...
