Development and testing of high-energy optical parametric amplifiers for multispecies differential absorption LiDAR within LEMON H2020 project
Abstract
During LEMON project (Lidar Emitter and Multi-species greenhouse gases Observation iNstrument - European Union’s Horizon 2020 research and innovation program 821868), we developed and tested OPO and OPA setups, in order to provide advances for multi-species differential absorption Lidar (DIAL) emitters. The targeted gas species and ad hoc wavelengths were H2O and its isotope HDO at 1982 nm, CO2 at 2051 nm, and CH4 at 2290 nm, with the prospect of demonstrating the possibility to emit the required energies (~30 mJ levels) for future spaceborne integrated-path DIAL systems. This was enabled by the use of high aperture periodically poled KTP crystals (PPKTP), specifically developed for the project, which were also radiation tested.
