Abstract:
A description is given of the method and apparatus for determination of the effective temperature and composition of a jet of products of the interaction of laser radiation with a glass-fiber-reinforced plastic and an organic plastic. Measurements are also possible of the temperature and emissivity of a target when it is exposed in atmospheric air to cw CO2 laser radiation with a flux density of 3 X 102 – 103 W/cm2. The products of damage to the glass-fiber-reinforced plastic consisted of particles of metal oxides with a diameter d32 = 2.3–3.5 μm and a volume concentration Cv = (0.06–0.25)X10 – 4, and of molecular gases CO2, H2O, and HCl; the damage products of the organic plastic were conglomerates of soot particles with the diameter d32 = 1–1.8 μm and a volume concentration Cv = (0.4–0.9) X 10 – 4, and the same molecular gases. The target emissivity increased with time and reached 0.8–0.9.
