Abstract:

A research program on laser irradiation effects on DMMP is reviewed, Physical and chemical effects of exposure to 0.6943 micron radiation from ruby lasers and 10.6 micron radiation from a CO2 laser were studied by a wide variety of laboratory techniques. Comparisons and conclusions relate to the practicability of laser irradiation for decontamination and protection purposes. Ruby laser effects of vapor fog nucleation are not observable without extremely high intensities, and even then, physical condensation requires very carefully controlled laboratory conditions. Ruby lasers produce very little chemical decomposition, at the power levels available in this study, and require intensities at least sufficient to produce dielectric breakdown at the laser frequency. The CO2 laser produces chemical decomposition products do not differ from simple heating effects, but are of sufficient magnitude to justify further laboratory studies. Author
