Abstract

Abstract: We have developed a low-noise optical-to-microwave frequency divider based on a femtosecond erbium fibre laser. The source of an optical signal was a He – Ne/CH4 frequency standard. Comparison of two frequency dividers showed that the relative instability of output microwave signals, introduced by the dividers, is 10 -4 – 10 -16 for the averaging time τ = 1 – 100 s. The instability obtained corresponds to the requirements imposed on interrogative oscillators for time and frequency standards based on Cs or Rb atomic fountains.
