Optimization and application of Intense High-Order harmonics

Final Report Summary - OHIO (Optimization and application of Intense High-Order harmonics)

High-order harmonic generation (HHG) from the interaction of an intense laser field and a gas target is attracting a lot of attention, since it provides an interesting table-top coherent extreme ultraviolet (XUV) radiation source, and since it is becoming a reliable source with pulse duration in attosecond regime. However, one major problem is that the efficiency of HHG is extremely low, which limits its further application. To meet the demanding of different kinds of applications, the pulse energy needs to be improved, the beam properties need to be fully characterized and better controlled. The OHIO project was devoted to optimize this beam source and to explore some of its applications.

More details are given in the publishable summary which is attached.
