Self‐Induced Phase Locking of Terahertz Frequency Combs in a Phase‐Sensitive Hyperspectral Near‐Field Nanoscope (Adv. Sci. 28/2022)

Hyperspectral Nanoimaging A hyperspectral terahertz near field optical microscope comprising a miniaturized quantum cascade laser frequency comb, acting simultaneously as a source and as a detector is presented. Quantum nanomaterials and related collective mode excitations can be probed at the nanoscale. More details can be found in article number 2200410 by Miriam Serena Vitiello and co‐workers.
