Atomic-transition lasers based on two-photon dissociation of metal-triiodide vapors.
Visible laser action on atomic transitions of Ga, In, Al, and Bi has been obtained by using an ArF excimer laser to photodissociate vapors of the corresponding metal triiodides. The excitation process involves sequential two-photon dissociation. Output energies of as much as 0.24 mJ at 417.2 nm and energy efficiencies of 2.9% have been obtained with Ga.
