摘要
在飞秒光脉冲自相关测量中,发现光电倍增管的双光子光辐射过程中的中间态和时间常数为几百飞秒的驰豫时间,采用微扰方法解布洛赫方程去分析信号光强的变化,证明中间态的寿命和失相时间对双光子光辐射以及对自相关曲线轨迹的影响。
An intermediate state of two-photon photoemission processes in a photomultiplier tube was found and relaxation with a time constand of a few hundred femtosecond was abserved by femtosecond time-correlatted measurements. Optical Bolch equation analysis of the signal in stensity was carried.
