Laser-induced fluorescence (LIF) using a pulsed laser is successfully applied in an argon plasma. The laser system consists of a pumping pulse laser fixed at 532 nm and a tunable dye laser. Using a homemade Fabry-Perot interferometer, the large linewidth of the original output is reduced by one order from 4 GHz to 340 MHz. The measured ion temperature is 0.15 eV with a velocity resolution about 200 m/s. It provides great possibility for the combination of LIF and planar LIF using the same pulsed laser system.
