Obstacle to Harnessing Laser-Driven Fusion
A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results and first-of-a-kind simulations of laser-plasma interaction.
Researchers at The Ohio State Univ. are evaluating a two-stage process in which a pellet of fusion fuel is first crushed by lasers on all sides, shrinking the pellet to dozens of times its original size, followed by an ultra-intense burst of laser light to ignite a chain reaction. This two-stage approach is called Fast Ignition, and there are a few variants on the theme.
