| Research Abstract |
A laser micro-thruster was experimental investigated in a vacuum chamber. In the experiment, 1-20 W continuous wave laser was irradiated on the thruster, consisting of an aluminum target, and thrust force proportional to the laser input power(0.3～0.8μN/W) was obtained. Because the thrust force depends on the pressure in the vacuum chamber, it is expected that a rarefied jet is formed around the aluminum target as a result of laser irradiation.
