Intensity Correlated Spiking Emission Due to Cooperative Effects in Alkali Vapors

TL;DR

This paper investigates how cooperative effects in alkali vapors lead to intensity-correlated spiking emission in frequency up- and down-converted radiation under continuous-wave laser excitation.

Contribution

It demonstrates that cooperative effects cause spiking behavior and intensity correlations in alkali vapor emissions, a novel insight into their emission dynamics.

Findings

Spiking behavior observed in alkali vapor emissions.

High intensity correlation between up- and down-converted radiation.

Cooperative effects are responsible for these phenomena.

Abstract

Spiking behavior and a high degree of intensity correlation of frequency up- and down-converted directional radiation from population-inverted alkali vapors excited with a continuous-wave laser pumping are attributed to cooperative effects.
