Many groups report laser‐induced isotope separation

In an exciting post‐deadline session at the Eighth International Quantum Electronics Conference in San Francisco this June five groups reported experimental results on laser‐induced isotope separation. One of the groups was able to separate small quantities of $U235.$ A successful method of doing this on a large scale would obviously be of great commercial interest and is undoubtedly the motivation of many workers in the field. It is clear that laser isotope separation will be the focus of considerable attention for quite a while.
