Abstract: The radiation intensities and absorption coefficients for ultraviolet radiation from wave front of laser sustained detonation waves, and the power densities of ultraviolet radiation passing through the wave front are studied numerically in this paper. Three kinds of transition processes, bremsstrahlung, free-bound and bound-bound transitions have been considered. The power levels of ultraviolet radiation we have computed show that attention to the ultraviolet radiation from wave front of laser sustained detonation waves should be paid.
