摘要
当高强度激光与非线性介质相互作用时，会产生激光谐波。在足够高的强度下，任何介质都会表现出非线性效应。我们使用1 μ m, 1-ps激光脉冲，在1013和1016 W/cm2之间的强度下观察到高阶奇谐波的产生，并测量了谐波的空间分布。高阶奇次谐波的存在以前已经在稀有气体中得到证实，其强度在1013到1014瓦/平方厘米之间。
Spatial Distribution of High Order Harmonics Generated in the Tunneling Regime
Production of laser harmonics occurs when a high-intensity laser interacts with a non-linear medium. At sufficiently high intensities any medium will show non-linear effects. We have observed high-order odd harmonic generation using a l-µm, 1-ps laser pulse at intensities between 1013 and 1016 W/cm2, and we have measured the spatial profiles of the harmonics. The existence of high order odd harmonics has previously been demonstrated1 in noble gases using intensities between 1013 and 1014 W/cm2.
