Shima’s article on self-compression of mid-IR pulses, and their application to solid-state high-order harmonic generation was published in the Journal of the Optical Society of America B (https://doi.org/10.1364/JOSAB.35.000A27). This result marks an important step towards the generation of attosecond optical pulses using solid-state high-order harmonic generation. The collaboration with Alexis Chacón, of Los Alamos National Laboratory, was enabled by funding from Oak Ridge Associated Universities.
