The laser blow-off method for injecting atoms into a tokamak plasma provides information about a number of plasma parameters. The injection of medium- and high-Z atoms enables global transport properties such as diffusion coefficients and radial and toroidal plasma velocities to be determined, whereas low-Z atoms such as lithium, carbon and sodium are used to measure local electron density and temperature profiles at the location of injection. Methods and results with the laser blow-off technique as a diagnostic tool are described and presented.
