Recent developments in laser techniques for the diagnostics of partially ionized plasmas such as arc-discharge are reviewed. Since laser measurements may provide excellent temporal and spatial resolution and possibility of non-intrusive nature, compared to other conventional techniques, it may be said that laser measurements are a new diagnostic tool for plasma. This report presents both methods and applications of interferometry, laser scattering, spectroscopy and laser velocimetry to the determinations of electron temperature, electron densities, species concentrations and flow velocity. The basic principles of these methods are described and their advantages and practical limitations are discussed.
