Experimental results show that it can reduce the fluctuation of laser output from about 60% to 5%, and it can also be used as a linear laser attenuator with good performance.
实验结果表明，它可将激光输出功率起伏由60%左右降到5%以下，并且此装置可作为线性很好的光衰减器。

By using a series and shunt combination of optocouplers the attenuator can be configured to produces a constant input and output impedance, regardless of where the voltage control setting is.
