Transmission spectra were measured and absorption coefficients were determined for gas condensate and oil using laser radiation with wavelength 1.07 μm. The dependences of the reflection coefficient on the laser-radiation angle of incidence on the surface of oil, gas condensate, and diesel fuel were obtained. Threshold intensities of laser radiation providing stable ignition and subsequent self-sustaining combustion of hydrocarbons on water and ice surfaces were experimentally determined. Laser afterburning (scanning) of heavy oil fractions remaining on the water surface after self-sustaining combustion was performed for the first time.
