Recent progress in high-brightness coherent XUV sources based on high-order harmonic generation

摘要

Precise phase matching and energy scaling of high-order harmonic generation enables us to obtain sub-microjoule up to microjoule optical energy in the XUV and soft-x-ray regions. Because of its good spatial profile and coherence, we can expect to achieve a focused intensity of 10~(13)-10~(14) W/cm~2, which will be used to explore the ultrafast nonlinear optics and ultrashort pulse generation in the attosecond regime.
