摘要
本文首先介绍频率分辨光学门 (FROG)技术的原理和算法。对于倍频情况 (SHG- FROG) ,我们编程实现了利用计算机快速回归。文中给出了利用该程序所获得的回归结果及对传统算法的改进。事实证明 。
The paper presents the theory and algorithm of the developing and applying frequency-resolved optical gating (FROG) method for retrieving the amplitude and phase of an ultrashort laser pulse. For frequency-doubling configuration (SHG-FROG), we program the computer to retrieve the amplitude and phase of the pulse. We give the retrieved results got by the improved program. The algorithm is proved to be robust and handy for diagnosing ultrashort pulses with varying characteristics.
