Relations between the physical properties in an iodine (I2) seeded argon free jet and its visualized image by a laser induced fluorescence (LIF) method using a multi-mode argon ion laser are described. It is shown that the flinge patterns of LIF in the jet result from the DOPPLER shifts of the rovibronic absorption lines of I2 due to the flow velocity component in the direction of the incident laser beam. It is also shown that the intensity of LIF depends strongly on the rotational temperature of I2.
