Paper Abstract

We report on a DIAL emitter for remote sensing of greenhouse gases, capable of addressing the three species of interest (CO2, CH4 and H2O) for space applications with a single optical source. It is based on an amplified Nested Cavities Optical Parametric Oscillator (NesCOPO) around 2 μm. The source is single frequency over a wide range of tuneability between 2.05 – 2.3 μm, and shows a typical energy conversion efficiency of 20% toward the signal wave. Spectral analysis shows a linewidth better than 100 MHz. These performances are measured in the vicinity of absorption lines of interest for space remote sensing of the three gases.
