| Zusammenfassung | The first application of a fiber amplifier in a laser Doppler anemometer system is presented. Using a neodymium-doped fiber amplifier as optical preamplifier in a conventional 1064 nm LDA, a small signal gain of 30 dB and 35 dB SNR enhancement of the LDA radiation are achieved. The amplifier model, numerical and experimental results are described. |
