Comparing ultrastable lasers at 7 × 10(−17) fractional frequency instability through a 2220 km optical fibre network
Ultrastable lasers are essential tools in optical frequency metrology enabling unprecedented measurement precision that impacts on fields such as atomic timekeeping, tests of fundamental physics, and geodesy. To characterise an ultrastable laser it needs to be compared with a laser of similar perfor...
