The laser micro-impulse torsion pendulum has been developed in this lab. A thin glass plate of about 80{mu}m thick is made as the target holder where the propellant film sticks on. Such structure can be used for both the R-mode and the T-mode measurements. The minimal resolution of this apparatus is 3x10-9N.s. A package, which combines a 2W single LD with its lenses, is evaluated by the pendulum under R-mode and T-mode conditions, respectively, in this lab. the momentum coupling coefficient Cm is about 2dyn/W and the specific impulsion Isp is about 170s. A new conceptual fiber-distributed structure of laser micropropulsion system for microsatellites has been proposed and discussed in this article.
