Laser Stabilization for Doppler Lidar of the Ionosphere

Abstract

Until recently, no spectroscopic frequency references suitable for Doppler lidar have been available for atomic or molecular ions. In 2008 we demonstrated the first absolute frequency referencing of a laser to atomic ions in a discharge lamp. The reference was found to have stability of 350 kHz over a few seconds and 20 MHz over a period of a week under laboratory conditions. For this grant, we proposed to construct a discharge-based frequency reference for N2+ suitable for field deployment in a lidar system.
