Claim 5:
6. An inductive plasma acceleration apparatus, comprising a pulsed laser assembly, a pulsed discharge assembly, an exciting coil assembly, a solid-state working medium, a control assembly, and a bracket assembly, wherein the exciting coil assembly is electrically connected to the pulsed discharge assembly, such that the pulsed discharge assembly produces a strong pulse current in the exciting coil assembly during a discharge process to further excite an inductive pulse electromagnetic field around the exciting coil assembly;
the solid-state working medium is located on an optical path of a laser pulse emitted by the pulsed laser assembly, such that the solid-state working medium produces a gas pulse under an ablation action of the laser pulse, and the inductive pulse electromagnetic field is located on a circulation gas path of the gas pulse, such that the gas pulse is capable of entering the inductive pulse electromagnetic field; and
the pulsed laser assembly and the pulsed discharge assembly are both electrically connected to the control assembly to control a power and a frequency of the laser pulse emitted by the pulsed laser assembly, wherein a reflecting assembly capable of changing a direction of the optical path is disposed on the optical path of the laser pulse emitted by the pulsed laser assembly, such that the laser pulse is capable of accurately irradiating on the solid-state working medium based on a predetermined density distribution, the bracket assembly comprises a support pedestal and a tower disposed on the support pedestal, the exciting coil assembly is disposed on the support pedestal and coiled around the tower;
the solid-state working medium has a columnar structure, wherein one end abuts on the support pedestal and another end located inside the tower, and an outer wall of a portion of the solid-state working medium located within the tower is in contact with and connected to an inner wall of the tower;
the reflecting assembly comprises a reflecting pedestal suspended above the tower, as well as a third reflecting mirror and a lens which are disposed on the reflecting pedestal, the third reflecting mirror is located above the lens and has a reflecting surface facing towards the lens, an annular skirt extending downwards is disposed around the lens, the lens is located directly above the tower and faces towards an end of the solid-state working medium, and an annular nozzle facing towards the exciting coil assembly is defined between an inner wall of the annular skirt and an outer wall of the tower; and
the laser pulse emitted by the pulsed laser assembly irradiates on the end of the solid-state working medium after passing the reflecting surface of the third reflecting mirror and the lens.
