Objectif The availability of suitable laser sources is one of the key issues for the development of active optical instruments in future earth observation missions. The main objective of this project is to demonstrate the feasibility of a semiconductor based laser source to be used as a laser transmitter in a Differential- Absorption LIDAR (DIAL) system for the observation and monitoring of greenhouse gases in the atmosphere.The basic building block of the project is a monolithic Master Oscillator Power Amplifier (MOPA) consisting of a frequency stabilized Distributed Feedback (DFB) Master Oscillator (MO) and a multi-section tapered semiconductor Power Amplifier (PA). The required on-, off-line laser wavelengths will be generated in the DFB section and amplified and modulated in the PA section. The device will be fabricated, mounted in a module with the beam forming optics and completed with the stabilization and control electronics. The entire laser source will be designed so that it can be used as the transmitter unit of a Random Modulated CW LIDAR system enabling measurements of the atmospheric CO2 concentration by Integrated-Path Differential-Absorption (IPDA) LIDAR with no signal ambiguity over a distance of 30 km and accuracy in distance determination better than 10 m. As a proof of concept, the CO2 concentration along a 2-3 km test path will be measured on ground and compared with the results provided by an existing DIAL system. For the DIAL test, the receiver unit will be developed in addition.The achievement of the project objectives should provide a substantial progress in the availability of compact, and highly efficient laser sources for the detection and monitoring of greenhouse gases in future earth observation missions and therefore to improve the position of Europe in this field. In a more general context the project will pave the way of using high brightness semiconductor lasers in space applications requiring simultaneously high power, beam quality Champ scientifique natural sciencesphysical scienceselectromagnetism and electronicssemiconductivitynatural sciencesphysical sciencesopticslaser physics Programme(s) FP7-SPACE - Specific Programme "Cooperation": Space Thème(s) SPA.2012.2.2-01 - Key technologies enabling observations in and from space Appel à propositions FP7-SPACE-2012-1 Voir d’autres projets de cet appel Régime de financement CP-FP - Small or medium-scale focused research project Coordinateur UNIVERSIDAD POLITECNICA DE MADRID Contribution de l’UE € 300 951,00 Adresse CALLE RAMIRO DE MAEZTU 7 EDIFICIO RECTORADO 28040 Madrid Espagne Voir sur la carte Région Comunidad de Madrid Comunidad de Madrid Madrid Type d’activité Higher or Secondary Education Establishments Contact administratif Roberto Prieto Lopez (Dr.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée Participants (5) Trier par ordre alphabétique Trier par contribution de l’UE Tout développer Tout réduire III-V LAB France Contribution de l’UE € 599 573,00 Adresse 1 AVENUE AUGUSTIN FRESNEL CAMPUS POLYTECHNIQUE 91767 Palaiseau Cedex Voir sur la carte Région Ile-de-France Ile-de-France Essonne Type d’activité Other Contact administratif Denis Mazerolle (Dr.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée FRAUNHOFER GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG EV Allemagne Contribution de l’UE € 251 310,00 Adresse HANSASTRASSE 27C 80686 Munchen Voir sur la carte Région Bayern Oberbayern München, Kreisfreie Stadt Type d’activité Research Organisations Contact administratif Walter Krause (Mr.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée ALTER TECHNOLOGY TUV NORD SA Espagne Contribution de l’UE € 199 041,00 Adresse CALLE TOMAS ALBA EDISON 4 ISLA DE LA CARTUJA 41092 Sevilla Voir sur la carte Région Sur Andalucía Sevilla Type d’activité Private for-profit entities (excluding Higher or Secondary Education Establishments) Contact administratif Demetrio López (Mr.) Liens Contacter l’organisation Opens in new window Coût total Aucune donnée UNIVERSITY OF BRISTOL Royaume-Uni Contribution de l’UE € 390 180,00 Adresse BEACON HOUSE QUEENS ROAD BS8 1QU Bristol Voir sur la carte Région South West (England) Gloucestershire, Wiltshire and Bristol/Bath area Bristol, City of Type d’activité Higher or Secondary Education Establishments Contact administratif John Rarity (Prof.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée DEUTSCHES ZENTRUM FUR LUFT - UND RAUMFAHRT EV Allemagne Contribution de l’UE € 253 985,00 Adresse LINDER HOHE 51147 Koln Voir sur la carte Région Nordrhein-Westfalen Köln Köln, Kreisfreie Stadt Type d’activité Research Organisations Contact administratif Peter Derkes (Mr.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée
