Abstract

This paper describes a new method of instantaneously determining the fluorescence line profile of atoms. By scanning the wavelength of a flash- lamp-pumped dye laser linearly across the resonance line of atoms, the line profile can be determined during a single laser shot. This method is useful for measuring the transient velocity distributions of various particles. Some applications of this method to plasma diagnostics for large devices such as tokamak are discussed.
