The conversion efficiency of the average power is 4.2% from pump diode to OPO signal output and the signal pulse duration is about 13 times shorter than that of the depleted pump light.

实验中获得的由二极管注入泵浦功率至opo信号光平均输出功率的转换效率达4.2%，信号光脉冲宽度比消耗后的泵浦光脉冲宽度压缩了13倍。

Sandwiching the solar cells inside the device would block some light out and knock down power conversion efficiency even further, Filler cautioned.
