摘要
完整地将光脉冲的时间分量和空间分量耦合到一起,使得时间矩阵元素内有空间变量,空间矩阵元素中也有时间变量,从而推导出描述克尔介质内飞秒光脉冲时空耦合特性的光束脉冲矩阵。理论上分析了钙离子红外自终止激光和紫外复合激光存在同时振荡的可能性,通过改进实验装置,首次获得钙离子的红外和紫外激光的同时振荡,二束激光输出总平均功率约70mW,其中红外和紫外激光约各占一半。比较了不同谐振腔对激光输出特性的影响,测量并分析了激励电脉冲与所产生二束激光脉冲波形的关系。
Abstract
With the temporal components and spatial components combined in one matrix so that the temporal elements include spatial variables and vice versa. The ray matrix which describes the spatial and temporal characteristics of femtosecond pulse in the Kerr medium is obtained.The simultaneous oscillations of calcium ion recombination and self-terminating laser is analysed theoretically and obtained in the experiment for the first time through improving discharge circuit and cavity structure. The maximum average output power reaches 70 mW. The photo-electro pulse waveforms is measured and discussed.
