摘要
采用量子力学算符方法确定了最小经典波包的Gauss型复函数表达式 .这些波包中心频率的取值可由位移参数和压缩因子任意调节 .结合真空中自由传播光波的实例 ,探讨了经典物理量的复函数表述和负频率的物理意义 .以复函数的实部和虚部分别表示横波的两个独立振动模式 ,而频率的正负则联系着圆偏振光偏振面的旋转方向和传播方向 .
The explicit expressions of minimum classical wavepackets are generally derived by using the operator technique of quantum mechanics.The problem of optical wavepackets travelling in vacuum is taken as an example to investigate the meaning of complex functions and negative frequency in classical physics.The central frequency of complex Gaussian wavepackets can be freely adjusted through the displacement parameter and squeeze factor. Some other characters of the minimum optical wavepackets are also studied.
