Abstract

We experimentally invistigate the optimal production of metastable xenon using RF discharge techniques combined with optical pumping from an auxiliary state in xenon. This provides a robust platform for producing large long-term metastable densities.

Optically enhanced production of metastable xenon

Garrett Hickman, J. D. Franson, T. B. Pittman

Metastable states of noble gas atoms are typically produced by electrical discharge techniques or “all-optical” excitation methods. Here we combine electrical discharges with optical pumping to demonstrate “optically enhanced” production of metastable xenon (Xe*). We experimentally measure large increases in Xe* density with relatively small optical control field powers. This technique may have applications in systems where large metastable state densities are desirable.

Proposed optical pumping of a metastable beam of 3He

Daniel E. Murnick, Ping Mei

A scheme for production of polarized beams of metastable 3He has been described. This scheme takes into account the recent advances in laser technology to optically pump 3He in the metastable 3S1 state and subsequent collisional transfer to ground state atoms. (AIP)

Maximizing optical production of metastable xenon

H. P. Lamsal, J. D. Franson, T. B. Pittman

The wide range of applications using metastable noble gas atoms has led to a number of different approaches for producing large metastable state densities. Here we investigate a recently proposed hybrid approach that combines RF discharge techniques with optical pumping from an auxiliary state in xenon. We study the effect of xenon pressure on establishing initial population in both the auxiliary state and metastable state via the RF discharge, and the role of the optical pumping beam power in transferring population between the states. We find experimental conditions that maximize the effects, and provide a robust platform for producing relatively large long-term metastable state densities.
