PAY ATTENTION, BIGGEST GUN IN THE WORLD---> Laser Fusion’s Brightest Hope

To minimize this sort of destruction, the amplifiers and other laser sections can be accessed only through a portable clean room or a specialized box that can form a tight seal. The laboratory has also built a small industry around damage mitigation. After a laser shot, engineers can use a telescope in the target chamber to look back through every line of optics for damage; each defect gets a number. They then use blue LEDs to program liquid-crystal-based screens through which beams pass before amplification. These screens can be made to have any arbitrary pattern of transparent and opaque areas , creating dark spots in a beam in order to circumvent damaged areas down the line. When too many defects accumulate, the engineers remove the damaged component and send it to another building, where the surface is re-treated and carbon dioxide lasers are used to etch out damage, l...
