… Abstract: We report on high harmonics generation in zinc oxide thin-films driven by an all-solid
fiber-based architecture. The laser delivers 41 nJ 70 fs … In this communication, we explore
the potential of such soliton-based fiber driver for HHG in thin-films of zinc oxide. Using the
same soliton-based driver, we propose an all-solid fiber architecture producing 1.4 MW
peak power 20 fs pulses out of a standard telecom singlemode fiber by soliton self-compression,
likely to enhance HHG. …

High-harmonics generation (HHG) in solids require high-energy few-cycle laser drivers at
near-to mid-infrared wavelengths with excellent beam quality to reach fluences of~ 1
TW/cm2. Along this line, soliton sources based on large mode area silica-core singlemode
fibers produce ultrashort (70 fs) pulses at remote wavelengths with hundreds of nJ, thus
providing a new platform for driving HHG in solids. In this communication, we explore the
potential of such soliton-based fiber driver for HHG in thin-films of zinc oxide. The laser …
