超短和聚焦激光脉冲的时间重叠是一项特别具有挑战性的任务，因为这个时间尺度低于快速电子设备的典型范围。在这里，我们提出了一种光学技术，允许测量两个聚焦和超短激光脉冲之间的时间延迟。这种方法实际上适用于两个激光器的任何聚焦几何形状和相对强度。这种技术的实验实现提供了良好的定量协议与理论预期。所提出的技术将被证明是非常有益的高功率多光束激光实验。
Temporal overlapping of ultra-short and focussed laser pulses is a particularly challenging task, as this timescale lies orders of magnitude below the typical range of fast electronic devices. Here we present an optical technique that allows for the measurement of the temporal delay between two focussed and ultra-short laser pulses. This method is virtually applicable to any focussing geometry and relative intensity of the two lasers. Experimental implementation of this technique provides excellent quantitative agreement with theoretical expectations. The proposed technique will prove highly beneficial for high-power multiple-beam laser experiments.
