Paper Abstract

This paper is devoted to investigations of the interaction of laser radiation with micron-size particles suspended in distilled water. Copper vapor laser and iron, boron carbide, silver, plastic (latex) particles were used in experiments. Required light power density was created either in traditional optical set-up, where laser radiation was focused in cuvetter with suspension by the lens, or in schemes where a laser active element was used as image brightness amplifier. In the latter case, the suspension that served as one of the reflectors of resonator formed required intensity distribution due to imaging of a mask placed on another mirror of resonator. High-speed motion of absorptive particles was observed in that scheme. Theoretical estimate 105-106 cm/s, based on suggested mechanism of interaction, was in good agreement with experimental data. Various behavior of absorptive (iron, boron carbide, silver) and partly transparent (latex) particles under laser radiation was observed and discussed. Particularly, the treatment of quarts plate by absorptive particles and accumulation and blurring of weakly absorptive particles on quarts plate are discussed.
