Abstract
The invention discloses a laser ablation micro-thruster comprising a shell and a power source supplying power to each electric unit. The shell is of an L-shaped structure. A micro-laser-device and an optical lens which reflects and focuses an optical path are arranged in the transverse portion of the shell. An optical window is formed in the inner side wall of the transverse portion of the shell. A metal target material is installed on the inner side wall of the vertical portion of the shell, wherein the metal target material generates micro-thrust through laser ablation. The metal target material comprises a glass layer which is installed on the shell and has the isolating and supporting functions. A brass layer which has the thrust function after laser ablation adheres to the glass layer through a binding agent layer. The optical lens is arranged on the transmission optical path of laser of the micro-laser device, and the optical window is arranged on the reflecting optical path of the optical lens. The micro-laser device is connected with a refrigerating device. The micro-laser device and the refrigerating device are connected with the power source through cables. The laser ablation micro-thruster is simple in structure, stable in performance and suitable for actual tests and actual use.
