1. A device for producing a hot plasma comprising a pressure vessel provided with an outer housing and an inner apertured liner in the shape of a paraboloid; at least two additional apertured walls positioned between said liner and said outer housing, all of said walls and said liner being in respective spaced relation to define respective nested chambers therebetween, means for feeding liquid lithium into said vessel within said liner; means coupled to said vessel for rotating it at a desired speed thereby creating a void area in the liquid lithium such that the free liquid mirror-like surface of said lithium forms a paraboloid of revolution having an axis of symmetry coaxial with the axis of rotation of said pressure vessel; a bottom outlet provided in said vessel and coupled between one of said chambers and said lithium feeding means; an inverted conical mirror with a half-angle of 45.degree. provided with a hole at its apex and positioned above said void area; a plurality of pulsed lasers positioned in such a manner as to provide a plurality of respective pulsed laser beams directed in paths perpendicular to and toward said axis of symmetry and toward the surface of said conical mirror, said mirror redirecting said beams in respective parallel paths with respect to said axis of symmetry, said redirected laser beams being reflected and focused by said lithium mirror-like surface to a common focal point of said paraboloid; a fuel pellet injection means positioned above said mirror and void area; and a plurality of fuel pellets adapted to be sequentially injected by said injection means through said hole in said mirror apex to said paraboloid focal point in timed sequence such that each pellet reaches said focal point at the same time as all of said pulsed laser beams arrive at said focal point; said liner being provided with a plurality of partitions sub-dividing the free liquid surface of said paraboloid of revolution of said liquid lithium; and the top of said pressure vessel being provided with an opening which is adapted to be connected to a spray condenser, whereby each of said sequentially injected fuel pellets is compressed and imploded by said plurality of pulsed laser beams to thus provide a substantially hot plasma and the consequent production of neutrons and x-rays. 2. The device set forth in claim 1, wherein said pulsed lasers are neodymium glass lasers, and each of said fuel pellets is a frozen deuterium pellet.
