Abstract

Preferential excitation of the ³P^°₁ state of the lead atom and enhanced emission in the Pb(³P ^°₁Pb(³P^°₁→ ¹D₂) transition at 722.9 nm have been observed following the detonation of lead azide, Pb(N₃)₂. The detonation is initiated by a short laser pulse and the products are expanded through a supersonic nozzle. It is suggested that the enhanced emission is due to preferential excitation of Pb(³P^°₁) via energy transfer from electronically excited N₂ combined with the effect of self-trapping of the emission from ³P^° ₁ to the ³P_0,1,2 states. The implications to short-wavelength chemical lasers are discussed.
