Determination of ultrashort light pulse shape by single-delay 3rd- and 4th- order intensity correlations
摘要
本文提出用单延迟三阶、四阶相关函数,经傅里叶交换获得脉冲形状的方法.在实验上用克尔快门测量了YAG被动锁模激光脉冲的三阶和四阶相关函数,并用该方法获得脉冲形状.文中还讨论了脉冲对称性对恢复脉冲的影响.
Abstract
The method for obtaining ultrashort light pulse shape based on Fourier transform by measuring the third-and fourth- order correlation functions T3(τ), T4(τ) is presented The T3(τ) and T4(τ) of the pulse from apassi-vely mode-locked YAG laser is measured experimentally by means of optical kerr shutter. The effect of the symmetry of the pulse on the recovery of the pulse shape is also discussed.
