Journal ArticleDOI
Multifilament-core fibers for high energy pulse amplification at 1.5 μm with excellent beam quality
Guillaume Canat,Sylvia Jetschke,Sonja Unger,Laurent Lombard,Pierre Bourdon,Johannes Kirchhof,V. Jolivet,Agnès Dolfi,Olivier Vasseur +8 more
TL;DR: A master-oscillator-power-fiber-amplifier laser source has been demonstrated using a 37-filament MFC fiber in the last amplification stage of single-mode amplification of narrow linewidth high peak power pulses.
Journal ArticleDOI
Tentative detection of clear-air turbulence using a ground-based Rayleigh lidar.
Alain Hauchecorne,Charles Cot,Francis Dalaudier,Jacques Porteneuve,Thierry Gaudo,Richard Wilson,Claire Cénac,Christian Laqui,Philippe Keckhut,Jean-Marie Perrin,Agnès Dolfi,Nicolas Cézard,Laurent Lombard,Claudine Besson +13 more
TL;DR: This is to the authors' knowledge the first successful attempt to detect CAT in the free troposphere using an incoherent Rayleigh lidar system and may serve as a test bed for the definition of embarked CAT detection lidar systems aboard airliners.
Journal ArticleDOI
High Brightness 1.5 μm Pulsed Fiber Laser for Lidar: From Fibers to Systems
Guillaume Canat,Laurent Lombard,Agnès Dolfi,Matthieu Valla,Christophe Planchat,Béatrice Augère,Pierre Bourdon,V. Jolivet,Claudine Besson,Yves Jaouën,Sylvia Jetschke,Sonia Unger,Johanes Kirchhof,Evguenii Gueorguiev,Christophe Vitre +14 more
TL;DR: In this paper, the authors discuss the designs and performances of narrow-linewidth erbium-ytterbium fiber MOPA for coherent detection lidars and present the first results of pulsed fiber lidar wake vortices detection using a coherent detection laser.
Set-up of a ground-based Rayleigh lidar to detect clear air turbulence
Alain Hauchecorne,Charles Cot,Francis Dalaudier,Jacques Porteneuve,Thierry Gaudo,Richard Wilson,Claire Cénac,Christian Laqui,Philippe Keckhut,Jean-Marie Perrin,Agnès Dolfi,Nicolas Cézard,Laurent Lombard,Claudine Besson +13 more
TL;DR: In this paper, a ground-based Rayleigh lidar was designed and implemented to remotely detect and characterize the atmospheric variability induced by gravity waves and turbulence in vertical scales between 10m and 1000m.
1.5µm LIDAR for Helicopter Blade Tip Vortex Detection
TL;DR: In this paper, a 1.5 μm LIDAR sensor dedicated to tip vortex characterization and tests on ground during trials on a DLR helicopter in hover flight is presented.
