Most effort so far has gone into laser isotope separation, for which several methods are available, but important applications for the future include some interesting topics in biochemistry.
New laser techniques, pulsed and continuous, which make it possible to see optical spectra without Doppler broadening, to label energy levels, and to enhance sensitivity, are now opening new applications.
Once exotic and time‐consuming, wave‐mixing spectroscopy has burgeoned into a set of techniques that can handle systems—flames, plasmas, luminescent crystals—inaccessible to conventional methods.
A new branch of optical spectroscopy that deals with the optical analogs of spin transients such as NMR is providing unique ways to explore dynamic interactions in optically excited atoms, molecules and solids.
