Coherent extreme ultraviolet (EUV) or X-rays is an important tool for the study of many exotic phenomena in nature. Until the last decade, spatially coherent X-rays were generated using large synchrotron facilities in the duration of ~ 100 fs and very few national facilities such as Free Electron Lasers (FELs). Due to its large infrastructure and a high cost of operation until now these facilities remain inaccessible to many researchers around the world. In the last decade, Ti:Sapphire based lasers centered at 800 nm have been extensively used to generate coherent X-rays by driving the process of high-harmonic generation (HHG) in atoms but limiting the cut-off photon energy to <250 eV. The cut-off energy of the HHG can be dramatically extended if the HHG process is driven by a long wavelength laser. The talk will focus on the development of a long infrared pump laser to extend the cut-off energy of the coherent x-rays to a few keV regimes.
