Properties of Light Produced by Nonlinear Optical Devices (Physics)

将对光的量子方面进行四项研究：(1)高阶压缩的自然多模推广的检验；(2)计算非线性光相互作用对经典光行为的偏离界限；(3)研究三阶和高阶次谐波产生过程；(4)检查相位涂抹泵浦光束对其产生的非经典状态的影响。为了理解非线性光学器件输出和宏观强度场中的噪声特性，需要对电磁场的量子涨落进行这样的研究。

Four investigations of quantum aspects of light will be undertaken: (1) an examination of a natural multimode generalization of higher order squeezing, (2) calculation of bounds on the deviation from classical behavior of light from nonlinear optical interactions, (3) study of third and higher order subharmonic generation processes, and (4) examination of the effect of a phase-smeared pump beam on the nonclassical nature of the states it produces. Such studies of the quantum fluctuations of the electromagnetic field are needed to understand the noise properties in the output of nonlinear optical devices and in fields of macroscopic intensity.
