The GEKKO XII Laser was completed in 1983 and is one of the world’s few large-scale laser facilities. To date, it has been instrumental in laser fusion research and has driven several achievements in the area, such as the generation of plasma with temperatures greater than one hundred million degrees Celsius, and the compression of matter to a density greater than 600 times its solid density by laser implosion.
The GEKKO XII Laser has two plasma generation vacuum chambers for conducting experimental studies. In Chamber I, a target can be irradiated by twelve laser beams arranged with spherical symmetry. In Chamber II, a target can be irradiated at high power from a single direction by combining the twelve individual beams into a single laser beam.
