A high power efficient Eh6G dye laser pumped by a copper vapor laser was developed with longitudinally pumped geometry and jet stream on the basis of this theory.

As the feed stream flows through the choke, the resulting J-T expansion and cooling causes some gas and most of the water vapor to liquefy.

A kinetic study was made on the sorption of water vapor carried in a stream of air by pelleted molecular sieves of the A-type made in this country.
