摘要：

Time-resolved spectroscopy using a combination of a monochromator, streak camera, image intensifier and CCD camera is conducted to investigate the radiative flow field generated in the in-tube laser propulsion configuration. A 5-J CO2 TEA laser beam is focused through a specially-designed, double-reflection optical system in atmospheric air. Radiation emission in the wavelength range of 320 to 850 mn is observed during a typical period of 10 mus.
