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…

Which transition can be used in sodium mirrorless lasing for mesospheric magnetometry?
Yucheng Yang, Chunyang Lei, Kai Guo +1
Directed mirrorless lasing from the mesospheric sodium layer has been proposed as a way to overcome the isotropy of laser-guide-star fluorescence, with demonstrated cell-scale anal…

Optimization of the Repumping Parameters for a Sodium Laser Guide Star Magnetometer
Yucheng Yang, Chunyang Lei, Kai Guo +1
A sodium laser guide star operated as a mesospheric magnetometer modulates a 589 nm laser at the local Larmor frequency and usually diverts a fraction of its power to a repumping l…
