Zusammenfassung: | The experimental scheme of 633nm and 1359nm good-bad cavity dual-wavelength active optical frequency standard is proposed, where He-Ne 633nm and Cs 1359nm stimulated emissions are working at good-cavity and bad-cavity regimes, respectively. The cavity length is stabilized by locking the 633nm output frequency to a super-cavity with the Pound-Drever-Hall (PDH) technique. The frequency stability of 1359nm bad-cavity stimulated emission output is then expected to be further improved by at least 1 order of magnitude than the 633nm PDH system due to the suppressed cavity pulling effect of active optical clock, and the quantum limited linewidth of 1359nm output is estimated to be 72.5 mHz. |
