Abstract
Abstract
We present time resolved, spatially integrated spectra of aluminium II oxide formed from the condensation of an aluminium laser plasma in air. The spectra show a revival of the emission from aluminium oxide molecules at 35µs after the plasma ignition. Thermodynamic calculations, together with temperature measurements, indicates that as the plasma cools, the aluminium oxide molecule forms through two different channels, explaining its increased presence.
