[hal-01098466] Multispecies high-energy emitter for CO_2, CH_4, and H_2O monitoring in the 2 μm range

We demonstrate the first emitter, based on a single optical source device, capable of addressing three species of interest (CO2, CH4, and H2O) for differential absorption Lidar remote sensing of atmospheric greenhouse gases from space in the 2 μm region. It is based on an amplified nested cavity optical parametric oscillator. The single frequency source shows a total conversion efficiency of 37% and covers the 2.05–2.3 μm range.
