“…The receiver system in the demonstrator used for comparison uses a 200 mm diameter telescope and a 1 mm InGaAs PIN detector. Further details on the MERLIN demonstrator is found in [3] and for the laser system specifically see [9]. The upconversion based receiver system consists of four main parts: An 8" Cassegrain telescope, beam scaling and guiding optics, the upconversion module, filters and the visible PMT.…”

For the first time an upconversion based detection scheme is demonstrated for lidar measurements of atmospheric CO 2 -concentrations, with a hard target at a range of 3 km and atmospheric backscatter from a range of ∼450 m. The pulsed signals at 1572 nm are upconverted to 635 nm, and detected by a photomultiplier tube, to test how the upconversion technology performs in a long range detection system. The upconversion approach is compared to an existing direct detection scheme using a near-IR detector with respect to signal-to-noise ratio and quantum efficiency. It is for the first time analyzed how the field-of-view of a receiver system, for long range detection, depends critically on the parameters for the nonlinear upconversion process, and how to optimize these parameters in future systems.

“…Moreover high power architectures (OPO-OPA), benefit from the availability and reliability of high energy Neodymium lasers at 1 µm, which are mature for spatialization. This is especially the case in the frame of the French German MERLIN (Methane Remote Sensing LIdar Mission) project [12,13]. One interesting aspect to be developed is also the ability to produce several wavelengths in the lines of interest.…”

-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.

I. INTRODUCTIONFor space-borne atmospheric LIDAR instruments, a manifold of scientific applications exists. But due to the lack of high energy laser sources providing the performance, reliability and lifetime necessary to operate such instruments in space, realization is seen by the community as still very critical.To overcome this, the FULAS (Future LASer Technology) project had been initiated by ESA supported by the German space agency (DLR), to develop and built a technology demonstrator and to verify its suitability for potential space missions. In order to cover the common need of possible future lidar missions, requirements for a generic laser source had been defined to achieve maximum usability of the laser concept and technology for future LIDAR missions.For definition of the baseline requirements, requirements of different potential LIDAR missions for Earth Observation had been evaluated. Depending on the mission, different types of lidar principles, e.g. Doppler wind lidar, backscatter lidar or DIAL, are applicable, requiring different kinds of laser transmitters (e.g. emitting single or double pulse, operating in burst mode, operating at different wavelength and pulse energy). Common for most of them is the need of a stabilized high quality and high energy laser source which can be based on a common solid state laser platform, if necessary in combination with suitable external frequency conversion to provide the required wavelength.The main goal of the design concept of FULAS is to get versatile technology building blocks. Therefore, beside the predefined nominal operation requirements (close to the specifications of the ATLID Atmospheric LIDAR of the Earth Care mission), the flexibility of the design to be adapted and customized for manifold potential future LIDAR missions will be demonstrated.One of the main issues with respect to lifetime and reliability of high energy lasers in space is the risk of degradation of optical coatings. The main focus here is on effects by Laser-Induced-Contamination (LIC), wherefore LIC risk mitigation is a major design criterion, demanding development of several innovative technology solutions to reach the design goal of reducing the amount of used organic materials to close to zero.The design was already presented at ICSO 2014 [1]. Since then it had been built and demonstrated its capabilities. As the technology will be the heart of the Methane Remote Sensing Lidar Mission (MERLIN) [4], [5] (DLR/CNES, Phase C in preparation), the test plan of FULAS was adjusted to support the MERLIN development needs. Therefore in the first instance only the Oscillator and Amplifier section, without UVconversion stage, of the presented FULAS laser, which is very similar to the one in preparation for MERLIN, had been assembled within the last year and integrated into the hermetical and pressurized housing. The optical performance in the IR had been demonstrated followed by successful operational thermal vacuum tests during Summer 2016 at the Airbus DS Test facilities.The UV-section wi...
