The polarization of helium (2 {sup 3}{ital S}{sub 1}) metastable atoms saturates at 50% when the ensemble is optically pumped with the {ital D}{sub 0} (2 {sup 3}{ital S}{sub 1}--2 {sup 3}{ital P}{sub 0}) transition. We have obtained polarizations app

We describe the current status of tunable, cw, solid‐state lasers in the infrared region of the spectrum which may be tuned to the helium resonance transition near 1083 nm. The principal use for these laser devices is the optical pumping of 3He and

We have developed a high‐density source of metastable neon and have selectively quenched both metastable species using a standing‐wave dye laser. The source is compact, stable, and produces an average intensity of 3.6×1014 sr−1 s−1 and a den

We describe and compare three methods we have used to stabilize the frequency of an end‐pumped, tunable La0.85Nd0.15MgAl11O19 (LNA) laser to the absorption lines of 4He or 3He near 1083 nm. The first two methods vary the thickness of an intracavity

This article gives a status report on the polarized 3He target development work at Mainz. It is based on the optical pumping of the 3S1 state of 3He with subsequent metastability spin exchange to the ground state atoms. This pumping scheme is very ef

Resonant two-photon ionisation of Na2 and subsequent third-photon dissociation of Na2+ has been studied with the use of a pulsed dye laser. Expressions for the time- and intensity-dependent populations of Na2+ and Na+ are derived and fit to observed

The authors have observed the alignment of the 5p /sup 2/P/sub 3/2/ state of strontium ions produced in Penning collisions between an unpolarized beam of helium metastable atoms and a strontium vapor target. The alignment is shown by a linear polariz

We have measured line shifts of the $3P\ensuremath{-}nD$ transitions in sodium induced by collisions with helium, argon, and krypton for $n=5 \mathrm{to} 18$. The shifts of the diffuse series transitions increase rapidly with principal quantum number
