Targets of a considerably non-stoichiometric composition and substrates of slanting cuts have turned to be necessary for the high-quality film growing. Multiple droplets and solid particles ejected from the target surface by the infrared radiation are removed successfuly from the laser-induced plasma by use of a velocity filter.3 pages, 2 figures, 1 tableSuperconductivityMaterials Sciencetext
