我们研制了一种用于干涉型引力波探测器的光电探测器，它可以探测到低本征噪声的高功率光。该探测器可以用一个InGaAs光二极管在1.064微米处探测功率大于100 mW的激光。使用谐振电路，实现了低本征噪声；噪声当量光电流为132µA。通过使用电路中使用的光电流限制器，我们确认即使在高功率(2W)入射到二极管上时，二极管也没有损坏。
We have developed a photodetector for interferometric gravitational wave detectors which can detect high power light with low intrinsic noise. The detector is designed to detect a laser power of more than 100 mW at 1.064 µm with a single InGaAs photodiode. Using a resonant circuit, low intrinsic noise is achieved; the noise-equivalent photocurrent is 132 µA. By using a photocurrent limiter used in the circuit, we confirmed that even with high power (2 W) incident on the diode, the diode was undamaged.
