Claim 8:
9. An inductive plasma acceleration method using the inductive plasma acceleration apparatus according to claim 6, comprising the following steps:
ablating the solid-state working medium by the laser pulse to produce a pulse gaseous ablation product, namely a pulse gas flow;
breaking down the pulse gaseous ablation product by a circumferential electromagnetic-field component of the inductive pulse electromagnetic field and establishing an annular plasma current; and
interacting with the plasma current by a radial electromagnetic-field component of the inductive pulse electromagnetic field to produce an axial Lorentz force to accelerate the plasma current, thereby achieving a propelling effect, wherein a yield and a pulse frequency of the pulse gaseous ablation product is controlled by controlling the power and the frequency of the laser pulse.
