Detector output electrical pulse signal amplitude is proportional to the energyof incident particle or ray, by measuring the pulse amplitude, get the energy of incident particles or rays.
Much attention is payed to the uniformity of pump beam in different condensing cavities. The outputenergy and pulse width are tested with different output mirror transmission.
重点研究了不同聚光腔的泵浦光场均匀性，同时在使用不同透过率输出镜时对激光输出能量和脉宽进行了测试。

The result indicates that the single pulseenergy and the Angle of divergence of output laser decrease, but the pulse width of output laser increases with the increase of the OPO cavity length.
