介绍了用于神光Ⅱ装置8路功率平衡的全自动精密小能量测量系统,并用自动控制半波片衰减装置对其性能进行了测定.系统稳定性精度优于1%(rms),量程可达三个量级范围.
Abstract
A full-automatic precision energy measurement system on small signal was described in detail, which was used for eight beams' power balance in Shenguang Ⅱ. An assembly attenuator of half-wave plate and polarizers is used to check up the performance of the system. The precision of stability precedes 1% (rms). And the measuring range covers three magnitudes. It enlarges the measuring range of the original measurement facility of Shenguang Ⅱ.
