Abstract

In this paper the implementation of a Nomarsky interferometer designed for the measurement of the specific impulse of propellants used in laser ablative propulsion are presented. The technique was first validated with known propellants. Subsequently, it was applied to the measurement of the specific impulse of binary metal/salt propellants developed by our research group [1]. This allowed the efficiency of these propellants to be determined.
