生成阿秒脉冲需要采用与以前的超快光学方法完全不同的方法。然而，阿秒测量技术建立在表征飞秒脉冲的既定方法之上：脉冲在离开其产生区域后进行测量。我们提供一种完全不同的方法：现场测量。也就是说，我们以可应用于许多高阶非线性相互作用的方式集成阿秒脉冲产生和测量。为了演示这种方法，我们结合了低强度（
Generating attosecond pulses has required a radically different approach from previous ultrafast optical methods. The technology of attosecond measurement, however, is built on established methods of characterizing femtosecond pulses: the pulse is measured after it has left the region where it was produced. We offer a completely different approach: in situ measurement. That is, we integrate attosecond-pulse production and measurement in a manner that can be applied to many high-order nonlinear interactions. To demonstrate this approach, we combine a low-intensity (
