Abstract

Impulse coupling coefficient C_m is one of the most important performance parameters in laser propulsion. C_m is the impulse increment of lightcraft that per joule laser beam energy acts on. The TEA CO₂ laser, whose single pulse energy is 100-Joule-class and wavelength is 10.6μm, is adopted by experimental research. In experimental environment cabin, the parabolic lightcraft is fixed on impact pendulum. Using Air, N₂, He, CO₂, N₂-He and N ₂-CO₂, different C_m is obtained. Experimental results indicate that C_m of the mixed gas is improved through changing gas component ratio.
