EOL Seminar: High Spectral Resolution Lidars with Single Telescope Design

Igor Razenkov

Wave Propagation Laboratory

During the past few years the Lidar Group at the University of Wisconsin-Madison (PI, Edwin Eloranta) designed several different High Spectral Resolution Lidar (HSRL) systems. These lidars were designed to be self-calibrated systems used for quantitative atmospheric aerosol measurements, as well as have eyesafe operation, and be able to operate unattended and continuously. The talk will discuss the problem of designing a stable and reliable mechanical and optical lidar coaxial transceiver with beam expansion via receiving telescope. This design approach was used to build three systems: Arctic HSRL (2005), GV HSRL (2008), and DOE HSRL (2011). All these instruments used an original method for locking laser frequency based on the stimulated Brillouin effect.  Igor will discuss what went right and wrong and how to make these instruments better in the future.
