When focusing YAG laser pulses at 266 nm into a heat-pipe oven containing PbI<sub>2</sub> molecules vapor, four red line emissions at 626.0, 619.8, 613.7 and 621.8 nm are observed. The photodissociation mechanism of PbI<sub>2</sub> molecules and the possible generation channels of these four line emissions are given. Moreover, the dependence of the emission at 626.0 nm on incident laser energy and heat-pipe temperature is measured. The experimental observation is well supported by the photodissociation mechanism proposed by us.
