ABSTRACTA number of diagnostics problems in the low temperature plasma generators have been analysed with special attention to the plasma spraying process, and a general approach to these problems has been proposed. The advantages, difficulties and limitations of optical nonintrusive methods have been discussed. Examples based on authors experience during last few years, are given.

This article presents the tendency of the changes of Nd-laser plasma parameters in dependence upon increasing target atomic numbers. In the experiment, the following targets — (C8H8)n, SiO2, Al, Cu, Ta, and Au — were investigated. For targets with Z higher than 13, the two-temperature plasma is observed with temperatures Te =500–600 eV and Te≅ 100 eV. Energy carried by ions from the low-temperature plasma can be higher than half the total energy carried by ions. The number of ions from low-temperature, X-ray-heated plasma can be by an order of magnitude higher than the number of ions from thermal plasma (Te = 500–600 eV).
