Synergy between laser linewidth and frequency chirp in mesospheric magnetometry based on the sodium laser guide star
Yucheng Yang, Chunyang Lei, Kai Guo +2
Mesospheric sodium magnetometry with a laser guide star measures the geomagnetic field near 90~km. Its sensitivity hinges on laser linewidth and chirp, yet prior work optimized the…
