Saturation Effects in Narrowband Resonance Lidar Measurements, Part 2: Potassium Lidar Systems and Experimental Results

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Resonance lidars targeting the D1 ${D}_{1}$ resonance line of potassium at 770 nm have been employed over the past 5 decades to yield numerous insights into the dynamics of the middle and upper atmosphere. It has long been recognized that these measurements can be severely affected by nonlinear behavior in the scattering process, that is ...

Rayleigh scattering

Applied Optics, 1981
We all know that blue skies and red sunsets are due to the “Rayleigh scattering” of sunlight. But beyond that, Rayleigh scattering means different things to different scientists.

Coherent Rayleigh Scattering

Physical Review Letters, 2000
The spectrum of coherent scattering induced by electrostriction in gases has been analyzed in the previously unexplored, free-molecule limit by solving Boltzmann's equation with a periodic force due to the optical fields. Calculated and measured spectra of several gases at rarefied conditions are nearly Gaussian with widths approximately 10% wider than
