FIELD: physics.
SUBSTANCE: reactor laser apparatus with direct pumping by fission fragments consists of a subcritical laser unit with an active substance (1) and an ignition pulse nuclear reactor surrounded by the subcritical laser unit. The active substance (1) includes a laser medium (4), non-threshold fissile nuclear material (7) and a neutron moderator (3). The ignition pulse nuclear reactor consists of a core which contains fissile nuclear material and a reactivity modulator (5). The fissile nuclear material with an ignition pulse nuclear reactor used is a threshold fissile nuclear material (9). The non-threshold fissile nuclear material (7) used in the subcritical laser unit is, for example, uranium-233, uranium-235 or plutonium-239. The threshold fissile nuclear material (9) used in the ignition pulse nuclear reactor is, for example, neptunium-237, plutonium-240, and at least one core.
EFFECT: high energy and power of the pumping pulse of the laser medium.
