Abstract:The output of a spin-flip Raman laser, pumped by a Q-switched CO2 laser, has been examined with a Fabry-Perot interferometer. It was found to consist of discrete lines, separated by the longitudinal-mode spacing of the spin-flip crystal. These lines do not move as the magnetic field is varied. As a result, the usefulness of a laser operated under these conditions as a spectroscopic tool is much reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
