The invention relates to the field of laser and material application, in particular to a multi-working-medium type laser plasma micro-thruster which comprises a laser, a laser height adjusting mechanism, a multi-working-medium system and a working medium switching mechanism. The laser is arranged on the support table and is aligned with the multi-working-medium system, the multi-working-medium system comprises a fixing frame and material fixing plates provided with different working media, all the material fixing plates are arranged in the fixing frame, and the fixing frame is driven by the working medium switching mechanism to rotate. According to the invention, the material fixing plates of different working media can be converted to act with the laser according to needs, so that adjustment of specific impulse, thrust and impulse can be realized by using different working media, and application requirements are met.
