Abstract

The CO₂ laser with wavelength 10.6 μm is adopted by experimental research. In experimental environment cabin, the parabolic lightcraft is fixed on impact pendulum. Using N₂, He, CO₂ and mutual mixed gas of N₂, He and CO₂, different impulse coupling coefficient C_m is obtained. It increases with enhancement of the pressure and molecular weight of the gases. In low pressure, it increases with enhancement of the bigger molecular ratio in mixture. In high pressure, it correlates with gas species and component ratio.
