摘要
研究了多模叠加态光场|ψI(ab)>q的等幂次N次方Y压缩特性,结果发现:态|ψI(ab)>q在一定的条件下恒处于等幂次N-Y最小测不准态,而不呈现等幂次N次方Y压缩效应。可见,在一定条件下由非对称相干态光场线性叠加所组成的多模叠加态光场仍可保留原光场的相干特性。
The paper presents the properties of N-th power Y-squeezing on multimode light field |φI(ab)>q . The finding is that in the some certain condition the state |φI(ab)>q can always display the equal-power N—Y minimum uncertainty state, but the state |φI(ab)>q can't display the equal-power N-th power Y-squeezing effect. It is obvious that in the certain condition multimode superposition state light field is composed of asymmetrical coherent state light field that always retains the coherent properties of original light field.
