This program will explore novel experimental approaches, aided by numerical simulations, to advance the science and technology needed to develop a next-generation XUV frequency comb. The overall objective will be the development of a coherent source capable of making a significant impact in precision spectroscopy and ultrafast science from the IR to the XUV. A new technique for highly sensitive measurements of optical nonlinearities and ionization dynamics is also proposed which utilizes the resonant response of the fsEC itself. This technique will enable the investigation of ways to control the ionization levels inside the fsEC. Furthermore, we propose to develop a coherent dual-comb XUV system. Dual-comb spectroscopy incorporates a second local oscillator frequency comb to enable heterodyne detection of individual comb components. We show that sufficient XUV power levels can now be achieved to enable the extension of this approach for the first time to the XUV.
