We present measurements of the power noise that is due to optical amplification in a laser-diode-pumped Nd:YAG free-space traveling-wave linear amplifier in a master-oscillator-power-amplifier configuration. The quantum noise behavior of the optical amplifier was demonstrated by use of InGaAs photodetectors in a balanced detection configuration, at a total photocurrent of 100 mA and in a frequency band from 6.25 to 15.625 MHz. The experimental results are in good agreement with predictions.
我们给出了在主振荡功率放大器配置下，激光二极管泵浦的Nd:YAG自由空间行波线性放大器中，由光放大引起的功率噪声测量结果。通过在平衡检测配置中使用InGaAs光电探测器，在总光电流为100 mA且频率范围为6.25至15.625 MHz的情况下，展示了光放大器的量子噪声行为。实验结果与预测结果吻合良好。
