| Zusammenfassung | With a neodymium-doped fiber amplifier a small signal gain of 40 dB at 1064 nm has been achieved. Using the same amplifier as an optical preamplifier in a conventional 1064 nm LDA, an improvement in the SNR of the LDA radiation and sensitivity enhancement in comparison to that for direct detection with a highly sensitive avalanche photodiode was obtained. |
