Transfer of laser frequency from 729 nm to 1.5 μm with precision at the level of 10-20
文献摘要：
By using a self-reference transfer oscillator method,two individual 1560 nm lasers with about 1.2 GHz frequency difference were phase locked to a 729 nm ultra-stable laser at two preset ratios.By measuring the beat frequency of the two 1560 nm lasers,fractional instabilities of 2×10-17 at 1 s and 2×10-20 at 10,000 s averaging time were obtained,and the relative offset compared with the theoretical value was 4.2×10-21±4.5×10-20.The frequency ratio of them was evaluated to a level of 1.3×10-20 in one day's data acquisition.This work was a preparation for remote comparison of optical clocks through optical fiber links.The technique can also be used to synthesize ultra-stable lasers at other wavelengths.
