Our article “All-optical sampling of few-cycle infrared pulses using tunneling in a solid” was published online in Photonics Research (doi: https://doi.org/10.1364/PRJ.420916, Early Posting pdf: https://www.osapublishing.org/prj/upcoming_pdf.cfm?id=420916)! This work was led primarily by Yangyang Liu, but with important contributions from current and former members of the LUMAS group. The work describes a variant on the TIPTOE (tunnel ionization with a perturbation for time-domain observation of an electric field) technique for characterizing laser waveforms, and we are excited about its future prospects for single-shot, on-chip waveform measurements!
