“…The results of experimental measurements of the CH4 concentration distribution along a 800 m sounding path with the OPO lidar system are shown in Figure 10. The background concentration of methane was calculated using the equation shown in Equation (2). The path averaged methane concentration of about 2.085 ppm over the path length of 800 m was retrieved.…”

A differential absorption lidar (DIAL) system designed on the basis of optical parametric oscillators (OPO) with nonlinear KTiOAsO4 (KTA) and KTiOPO4 (KTP) crystals is described. The crystals allow laser radiation tuning in the infrared region (IR) wavelength region. The measurements in the 3.30–3.50 μm spectral range, which includes a strong absorption band of methane, are carried out. Lidar backscattered signals in the spectral band 3.30–3.50 μm has been measured and analyzed along the horizontal path in the atmosphere. Based on the experimental results, CH4 concentrations ~2.085 ppm along a 800 m surface path are retrieved in the spectral range under study with a spatial resolution of 100 m.

“…For this kind of application several solid state laser approaches are being investigated, which are mainly based on injection seeded Ho or Ho:Tm laser oscillators at 2 µm for CO 2 concentration measurement [5,6], or based on injection seeded optical parametric devices [7][8][9][10][11]. Optical parametric devices are well suited since they provide wide potential tuning ranges and sufficient output energy especially in the mid-IR where laser options are scarce.…”

-We report on a DIAL emitter for remote sensing of greenhouse gases, capable of addressing the three species of interest (CO 2 , CH 4 and H 2 O) 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.
