摘要

本文提出了一种新方法，用于确定光学泵浦探针方案中聚焦元件焦平面的相互位置及其沿激光束传播轴的空间排列。该方法基于飞秒激光脉冲与物质相互作用产生的非线性吸收效应。该方法的实际应用实例是建立一个光学方案，利用电光门控法测量太赫兹脉冲的时间形状。

Method of Spatial Alignment of Focal Planes and Sample Positioning in the Pump–Probe Scheme

A new method is proposed for determining the mutual position of the focal planes of focusing elements and their spatial alignment along the laser beam propagation axis in the optical pump–probe scheme. The method is based on the effect of nonlinear absorption arising from the interaction of femtosecond laser pulses with matter. The practical application of this method is demonstrated using the example of setting up an optical scheme for measuring the temporal shape of a terahertz pulse with the electro-optical gating method.
