On the delayed emission from a laser-produced aluminum plasma under an argon environment
Garima Arora, Jinto Thomas, Hem Chandra Joshi
Abstract
We report long time (250 μs) emission from Al I in laser produced plasma in argon ambient and its dependence on laser power density, background pressure and distance from the target surface. Role of argon metastables as energy reservoirs is discussed.
