分束器上光束相位差的锁定

Phase Difference Locking on Beam Splitter

本文利用两种方法分别实现了５０：５０ 分束器上不同相位差的锁定， 输入功率与一般平衡零拍探测系统工作条件相同。锁定稳定度优于２％ ，

Any Phase difference of two beams is locked on 50:50 beam splitter with two different methods. It is useful for quadrature amplitude and phase measurement in homedyne system. The locking stability is better than 2%.
