介质中4MFSS光场广义磁场的Nj次振幅压缩效应

根据量子力学中的态叠加原理,构造了强度不等的非对称四态叠加多模泛函叠加态光场(即4MFSS光场)。利用多模压缩态理论,对介质中4MFSS光场广义磁场分量的不等幂次高次振幅压缩效应进行了详细的研究。结果发现:①在一定条件下,上述4MFSS光场的广义磁场分量可呈现出周期性变化的广义非线性不等幂次高次振幅压缩效应;②上述4MFSS光场其广义磁场分量所呈现的Nj次方高次振幅效应的压缩幅度,明显受到介质的增益系数或吸收系数的直接影响;对于增益介质而言,随着传播距离的增大,光场Nj次方高次振幅压缩现象的压缩程度加深、压缩幅度增大、压缩效应增强;对于吸收介质而言,随着光场传播距离的增大,光场Nj次方高次振幅压缩现象的压缩程度降低、压缩幅度减小、压缩效应减弱。

The Nj-th Power Amplitude-squeezing of Generalized Magnetic-field of 4MFSS Light Field in Medium

Based on the state superposition principle of quantum mechanics,asymmetrical multimode functional superposition state light field with the superposition of four quantum states is constructed.By using multimode squeezing state theory,this paper makes a detailed study of the unequal-power higher-power amplitude-squeezing of generalized magnetic-field of 4MFSS light field in medium and it is found that 1) under certain conditions,the generalized magnetic-field of 4MFSS light field shows periodical generalized nonlinear unequal-power higher-power amplitude-squeezing;2) the Nj-th power higher-power amplitude-squeezing shown in the generalized magnetic-field of 4MFSS light field is obviously affected by the coefficient of the gain medium or of the absorption medium.In the gain medium,when the light field spreading distance becomes farther,the extent,range and effect of Nj-th power higher-power amplitude-squeezing are intensified;in the absorption medium,when the light field spreading distance becomes farther,the extent,range and effect of Nj-th power higher-power amplitude-squeezing are decreased.
