Based on fundamental research of above-threshold-power laser radiation by C. Townes (laser beam splitting) and G. A. Askaryan (self-focusing and sublimation evaporation), a new highperformance technology for growing nanowhiskers of metal and their oxides, semiprecious crystals, and composite materials based on polycarbonate in open air is developed. Some possibilities of its practical applications are shown.
