摘要:

利用非共线双脉冲时域干涉技术在气体介质中产生高次谐波。该方法是基于这样的事实,即所产生的谐波继承某些光谱特性的驱动激光器。这两个时间延迟的超短激光脉冲,在所有参数相同,是由一个定制的分裂和延迟单元利用波前分裂没有显着的能量损失。该装置易于在任何阿秒脉冲产生光束线中实现,并且适合于产生具有简单且快速可变的中心光子能量的极紫外源,可用于广泛的应用。

英文摘要:

We generate high-order harmonics in gaseous medium with tunable photon energy using time domain interferometry of double pulses in a non-collinear generation geometry. The method is based on the fact that the generated harmonics inherit certain spectral properties of the driving laser. The two temporally delayed ultrashort laser pulses, identical in all parameters, are produced by a custom-made split-and-delay unit utilizing wave front splitting without a significant energy loss. The arrangement is easy to implement in any attosecond pulse generation beamline, and is suitable for the production of an extreme ultraviolet source with simply and quickly variable central photon energy, useful for a broad range of applications.
