Abstract

For the development of a variety of applications of high-order harmonics (HH), one of the most important issues is energy scaling. Recently, by using phase-matching process, high conversion efficiencies were achieved. In this study, as the next step, we investigated the energy scaling of the phase-matched HH. To satisfy the phase matching condition, a large energy pump pulse was loosely focused by a f = 5000 mm planoconvex lens into the long cell with a 10 cm interaction length.
