Continuous-wave laser thruster experiment

This paper reports the results of fundamental experiments on a continuous-wave CO, laser thruster. The laser-sustained plasma (LSP) was maintained in the pressure ranging from 2 to 7 atm with a laser power level of more than 300 W. The location of LSP can be controlled by adjusting laser power and focus position. Thruster performance was evaluated by measuring thrust using a simple thrust stand equipped with a load-cell sensor. Energy balance in the thruster was clarified by measuring heat loss and transparent laser loss. (C) 2000 Elsevier Science Ltd. All rights reserved.
