Frontiers of laser development

MAR 01, 1971
Supersonic gas flow, organic dyes and chemical reactions are among the systems exploited in the search for more power, narrower linewidths and greater tunability.
John L. Emmett

Early lasers had an extremely limited range of operational parameters, and so were of only limited usefulness. Now, however, laser action has been achieved in almost everything from semiconductor diodes to quinine water. What are some of the results of 12 years of laser research?
