This is one section of a laser amplifier tube from the Shiva experimental fusion apparatus, operated at Lawrence Livermore National Laboratory from 1978 through 1981. Scientists used the Shiva device to test theories about how lasers might be used to trigger a nuclear fusion reaction. The research program was part of the continuing quest to harness nuclear fusion as a source of energy.
Lasers are useful in this type of research since they emit such a narrow beam of intense radiation. Shiva focused the energy of twenty laser beams on a tiny target of fuel to determine how the fuel would react. This amplifier tube is a short section of one of the twenty beam paths and contains panels of neodymium glass that strengthen and focus the light beam. Device included in Shiva laser chain, 1977-81. Power amplification - maximum 20. Donor notes: "These amplifiers were used in Shiva, a twenty-arm pulsed glass laser which preceded the Novette and Nova lasers."
