Chinese scientists are making rapid progress in the field of laser technology. A beam containing 10,000 times more energy than all the world's power grids combined could create matter and antimatter and help physicists understand the origin of the universe. Another research project has developed a laser technique that can identify hidden objects more than a kilometer away. The technology could bring important advances to autonomous driving.
