The lasers we're all familiar with use visible light, the red lasers and green lasers. But I heard you refer to ultraviolet. Yes. So are these UV lasers instead? The laser itself, the solid state lasers that are used to create the beams and amplify the beams largely use neodymium in a glass media. And so it's much better, much more of the energy is absorbed and used for heating the plasma that then can start fusion reactions.
How did we achieve nuclear fusion? Neil deGrasse Tyson and comedian Chuck Nice learn about thermonuclear fusion, the world’s most powerful lasers, and harnessing nuclear power with operations manager at The National Ignition Facility, Bruno Van Wonterghem.
