Abstract

We report the recent progress of our work on the development of an optical frequency standard in the 1.5 micrometer region based on a Doppler-free acetylene absorption. We have developed compact and portable acetylene-stabilized diode lasers for practical use. We have realized the frequency stability and reproducibility of about 2 X 10^-13 and 2 X 10^-11 respectively using a third-harmonic signal detection. We have measured the absolute frequency of the acetylene transition with an uncertainty of about 10^-10 using a frequency chain based on a two-color mode-locked fiber laser. One of the important applications of the acetylene optical frequency standard is the WDM optical communication system, which requires precise absolute frequency references for a hundred of channel frequencies in the wavelength region of 1530 - 1565 nm. We have developed a wide-range heterodyne optical phase-locked diode laser using the acetylene-stabilized laser as a master in order to realize the WDM channel frequency standards.
