High brightness semiconductor lasers are potential transmitters for future space LIDAR systems. In this contribution, we propose an all-semiconductor laser source for an Integrated Path Differential Absorption LIDAR system for column-averaged measurements of atmospheric CO2 in future satellite missions. The transmitter design is based on two monolithic Master Oscillator Power Amplifiers, providing the on-line and off-line wavelengths close to the selected absorption line around 1.57 μm. Our design allows the emitters to deliver high power and high quality laser beams with good spectral properties. An output power above 400 mW with a SMSR higher than 45 dB has been demonstrated. On the side of the receiver, our results indicate that the major noise contribution comes from the ambient light. For this reason narrow band optical filters are used in the detection together with high sensitivity and low noise single photon counting techniques.
