Abstract
Temporal spiking of directional infrared and ultraviolet cooperative emission from sodium vapors excited to the $4D_{5/2}$ level with a continuous-wave resonant laser pump is analyzed. Mirrorless lasing at 2207 and 2338 nm on cascade population-inverted transitions and radiation at 330 nm generated due to four-wave mixing demonstrate a high degree of intensity correlation.
