Abstract
We in this paper report the progress on developing a "laser cooled Cs atomic fountain clock" at NIM. We also present scheme of the "femto-second pulse laser —comb frequencies" which was just started at NIM. As the f-second comb links optical wavelengths to Cs standard frequency and considering that our new Cs fountain clock is desired to achieve an uncertainty in the order of 10-15, these two projects are expected to advance the capability of optical wavelength measurements in this country to a new level in the near future. This work will also lay the technical foundation for developing optical clock as possible candidate for next generation of frequency standard. Key words: wavelength standard, frequency standard, Cesium clock, comb optical frequency.
