Properties of Light Produced by Nonlinear Optical Devices (Physics)

点击翻译按钮获取中文摘要

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.
