Abstract
The aim of the paper is to obtain an RF beat signal that has a stability similar to that of the laser lines. The setup consists of a CO/sub 2/ laser that uses two different isotopes of C and or O that oscillates at two optical frequencies in a single very high Q optical cavity. The output is mixed on a wideband photomixer to produce RF power at the difference frequency.
