Highly coherent two-color laser and its application for low-noise microwave generation

Nature Communications
Two-color lasers with high coherence are essential for precision measurements and low-noise photonic microwave generation. However, conventional two-color lasers often suffer from reduced coherence when the frequency spacing is large.

Measuring the gravity potential between two remote sites with CVSTT technique using two hydrogen clocks

Geo-spatial Information Science
According to General Relativity Theory (GRT), by comparing the frequencies between two precise clocks at two different stations, the gravity potential (geopotential) difference between the two stations can be determined due to the gravity frequency shift
