Overview

The mission of the Lab of Time and Frequency Technique is to carry on the research of femtosecond optical frequency comb (FOFC) and laser-cooling Cs fountain clock. The developed FOFC is used for measuring the absolute frequency of optical clock, generating microwave, and linking optical frequency of Sr lattice clock to microwave frequency of Cs fountain clock. The research of laser-cooling Cs fountain clock is intended to develop an ultra-...

  • Ultra-compact Cs Fountain Clock

    The research of ultra-compact Cs fountain clock was lauched in 2008. By the end of 2009, the preliminary equipment of the clock has been completed with a frequency stability of better than 5.210-15 in one day. Works to improve the uncertainty...

  • Ti: sapphire Femtosecond Frequency Comb

    A femtosecond optical frequency comb (FOFC) based on the Ti: Sapphire femtosecond laser is developed. The FOFC consists of a home-made Ti: Sapphire femtosecond laser, two spectral broadening parts...

  • Fiber Comb

    A femtosecond laser frequency comb based on an Er-doped fiber  laser is developed. The Er-doped fiber comb consists of an Er-doped fs fiber laser, a two-stage fiber amplifier, a highly nonlinear...
