“…Over the last decade, Doppler wind lidar systems (Reitebuch, 2012a) have emerged as a versatile tool for the range-resolved detection of wind shears (Shangguan et al, 2017), aircraft wake vortices (Köpp et al, 2004;Dolfi-Bouteyre et al, 2009), wind and temperature turbulence (Banakh et al, 2014) as well as gravity waves , amongst other applications. In particular, direct-detection wind lidars have been demonstrated to provide accurate wind information from 25 ground up to altitudes of 60 km (Dou et al, 2014) or even beyond (Baumgarten, 2010;Hildebrand et al, 2012).…”

The paper also highlights the relevance of accurate ground detection for the Rayleigh and Mie response calibration and wind retrieval. Using a detection scheme developed for the NAWDEX campaign, the obtained ground return signals are exploited for the correction of systematic wind errors. Validation of the instrument performance and retrieval algorithms was conducted by comparison with DLR's coherent wind lidar which was operated in parallel, showing a systematic error of the A2D LOS winds of less than 0.5 m·s -1 and random errors from 1.5 m·s -1 (Mie) to 2.7 m·s -1 (Rayleigh). 20

“…Des mesures de tourbillons avec un Lidar embarqué sur l'avion en configuration transverse ou axiale sont également possibles [6]. Les prochains défis pour des Lidars fibrés sur les aéroports sont la cartographie rapide de vents (360° en 1 mn) à longue distance (>10 km) autour des sites aé-roportuaires, et la cartographie de la turbulence de vent afin de pourvoir anticiper les trajectoires et prévoir les durées de vie des tourbillons de sillage.…”

“…They have many advantages, such as operation in eye-safe spectral regions, low-transmission losses in atmosphere and telecommunication fibers, and integration of easily available and cost-effective fiber communication components. Furthermore, they can be found in applications, e.g., free-space communications, light detection and ranging systems (LiDAR), range finding and remote sensing [1][2][3]. Coherent light sources built in MOPA configurations are advantageous in comparison with classical laser configurations.…”

Abstract:In this work, we demonstrate a three-stage all-fiber master oscillator power amplifier (MOPA) system emitting over 40 W of continuous-wave (CW) output power at~1.5 µm. The setup utilizes three self-fabricated high-power passive fiber components: a mode-field adaptor (MFA) and two types of pump and signal power combiners. Their development allowed us to become independent from commercially available components, which are often incompatible with fibers used in the experimental setups, resulting in additional losses. A power combiner with single-mode (SM) signal fibers in a configuration (5 + 1) × 1 was used in the second stage of the MOPA system, which was based on an SM Er-Yb co-doped double-clad (DC) fiber. The fabricated MFA was used to connect the second amplifier stage based on SM fibers with the third amplifier stage based on large-mode-area (LMA) fibers. In the third stage of MOPA system, based on Er-Yb LMA DC fibers, we used the fabricated power combiner based on LMA-type signal fibers in a configuration (6 + 1) × 1. The presented three-stage MOPA system, utilizing self-fabricated high-power passive fiber components, enables amplification of an input signal of 10 mW up to 44 W of the CW power at the wavelengths of 1555 nm and 1563 nm, corresponding to a gain level of approximately 36.4 dB.
