xuv的音标

It is well-known that the interaction of intense laser field with atoms and molecules can lead to high-order harmonic generation ( HHG). Coherent sources of radiation in XUV and x-ray regions can be obtained by HHG.

当高强度的激光场与原子或分子相互作用时可以产生高次谐波，人们可以利用高次谐波获得相干极紫外高频段辐射源XUV和X射线源。

Calculation shows that such a temporal structure can be reconstructed from the differential photoelectron energy spectrum excited by XUV or x ray, modulated by a laser field and measured at 90 ° or 0 ° with respect to the linear laser polarization.

可以由XUV激发惰性气体产生、并在与超短脉冲激光的线性极化方向成0°或90°的方向上测量得到的光电子能量微分谱重建这种时间结构。

A method is introduced to directly measure the temporal structure of femtosecond XUV which has a narrow bandwidth using sub-picosecond duration laser.
