Аннотация:
The stimulated emission at 722.9 nm is observed by a direct photodissociation of the PbI<sub>2</sub> molecules with a 266 nm pulse laser. The possible dissociation channels are discussed. Two-photon resonant photodissociation mechanism is used to explain the generation of the 722.9 nm emission. The emission is measured at different incident laser energy and heat-pipe temperature. The obtained experimental result is well supported by the photodissociation mechanism given by us.
