Abstract: | At high temperature, the transmission peaks of a Fabry-Perot cavity filled with rubidium show sharp structures when the frequency of the laser is close to the 5S - 5D two-photon transition. These structures correspond to a laser emission between 5D and 5P. The wavelength of this laser emission (7759 Å) is smaller than the exciting wavelength (7779 Å). |
