Abstract

Strongly amplified spontaneous emission (ASE) has been observed on he 366.5 nm UV broad-band transition in molecular sodium. Pump energy and Na₂-density dependences indicate clear thresholds for this emission in comparison with the well-known violet bands of Na₂. Simple gain calculations, based on ASE considerations support these observations. The emission appears to be a better candidate for proposed tunable laser action in the sodium molecule. Some new approaches are discussed.
