  • Device for quantum beam generation, method for quantum beam generation, and device for laser fusion
    Patent number: 10134492
    Abstract: The device has a target supply unit 4a for supplying a target 2a to a chamber 3a, a target monitor 5a for monitoring the target 2a present inside the chamber 3a, a laser light irradiator 6a for irradiating the target 2a present inside the chamber 3a, with laser light 8a, and a controller 7a. The target supply unit 4a emits the target 2a at a timing for emitting, that is controlled by the controller 7a, into a preset emission direction 3d inside the chamber 3a, and the controller 7a calculates an irradiation point 4d with the laser light 8a, calculates a timing for arriving of the target 2a at the irradiation point 4d, and makes the laser light irradiator 6a irradiate the target with the laser light, based on the irradiation point 4d and the timing for arriving.

  • A METHOD FOR PROCESSING ZIRCONIA
    Publication number: 20170341990
    Abstract: A problem to be solved is to provide a method for processing zirconia without producing a monoclinic crystal. The solution is a method for processing zirconia, including the step of irradiating the zirconia with a laser with a pulse duration of 10?12 seconds to 10?15 seconds at an intensity of 1013 to 1015 W/cm2.

  • Laser fusion device and nuclear fusion generating method
    Patent number: 9805829
    Abstract: A target shell monitoring device 4 that monitors an attitude and a position of the target shell Tg1, a compression laser output device 5a that irradiates the target shell Tg1 with a compression laser light LS1, and a heating laser output device 6 that irradiates the target shell Tg1 with a heating laser light LS3 following the compression laser light LS1 are provided. The target shell Tg1 has a hollow spherical shell shape, includes an approximately spherical space Sp on an inner side thereof, includes at least one through hole H1 connecting an outer side thereof and the space Sp, and includes, on an outer surface Sf1 thereof, irradiation areas Ar1 and Ar2 to be irradiated with compression laser lights.
