Nutzung diodengepumpter Faserlaser in der Laser-Doppler-Anemometrie/Application of diode-pumped fiber lasers for laser Doppler anemometry

Abstract: Laser Zentrum Hannover e.V. Diodengepumpte Faserlaser vereinigen den hohen Wirkungsgrad und einfachen, kompakten Aufbau von Diodenlasern mit der hohen Strahlqualität von Glaslasern. Sie erreichen derzeit über 30W Leistung mit hoher Strahlqualität in einem kompakten, kostengünstigen Aufbau. Daher sind Faserlaser für die Realisierung von portablen Laser-Doppler-Anemometern (LDA) hoher Leistung attraktiv. In diesem Aufsatz wird auf den aktuellen Stand der Entwicklung von Faserlasern und deren Einsatz für kompakte… Show more

“…Fibre lasers fulfil features (1), ( 2) and ( 8) excellently. In [54,55], the use of a diode-pumped double-clad Nd-doped glass fibre laser for LDV was reported. Fibre lasers with Fabry-Perot cavities have a typical line width of about ≈ 10 nm resulting in a small coherence length of l C = λ 2 / = 113 µm, with centre wavelength of λ = 1064 nm, see equation (3).…”

“…However, mode-beat frequencies with integer multiples of f ≈ 2 MHz can be observed within the signal bandwidth of the detector [36,55]. This might disturb the detection of the Doppler spectral line.…”
