Towards a Brillouin-LIDAR for remote sensing of the temperature profile in the ocean

For remote sensing of temperature profiles in the ocean Brillouin scattering can be exploited as a temperature tracer. Such a lidar system is capable of delivering cost-effective on-line data from an extended region of the ocean compared to conventional in situ techniques. The acquired temperature profiles can give valuable input to climate studies and weather forecasts. In this contribution we present the current status of our experimental setup, consisting of a light source based on a multistage pulsed Yb:doped fiber amplifier and a receiver unit based on an excited state Faraday anomalous dispersion optical filter. Both components are advancements of laboratory experiments and possess the potential to be operated from an aircraft
