The invention relates to a reflecting type laser-electromagnetic field coupling thrustor which comprises a laser system, an electromagnetic accelerating electrode assembly and a static electric fieldassembly. The electromagnetic accelerating electrode assembly comprises an electromagnetic accelerating cathode, an electromagnetic accelerating anode and an electromagnetic accelerating electrode power source; the static electric field assembly comprises a static electric field accelerating electrode, a working medium and a static electric field accelerating power source, the static electric field accelerating power source provides power for the working medium and the static electric field accelerating electrode, and a potential difference is formed between the working medium and the static electric field accelerating electrode to form a static electric field; laser plasmas generated by ablation of the working medium by laser beams enter the static electric field, when the laser plasmas accelerated by the static electric field move to the position between the electromagnetic accelerating cathode and the electromagnetic accelerating anode, discharge arcs can be induced to be generated,the laser plasmas are heated by the discharge arcs and are further ionized, the laser plasmas are sprayed out in an accelerated manner under the joint effect of lorentz force and aerodynamic force, and thrust is accordingly generated. The reflecting type laser-electromagnetic field coupling thrustor has the beneficial effects that the thrust is adjustable, the thrust efficiency is high, and the thrust density is large.
